The SIP Abacus plus programme makes use of three tools to have a positive impact on children – Abacus, Brain Gym, and Speed Writing. With their initiation into the programme, children begin to enjoy numbers and develop / improve their skills of concentration, visual memory, listening resulting in increased self- confidence. The programme incorporates a lot of fun through games & puzzles too. The programme is designed in such a way that the child can attend the class twice a week with no homework and still be able to overcome their fear of numbers.

Additionally, Brain Gym Exercises are deigned to help the children relax and energize their brain to do new tasks. Children improve their ability to learn, do their school-work faster and hence have more free time to pursue their passion.

Programme Highlights

  • Training based on a structured international curriculum
  • Small batch size to ensure individual attention
  • Interactive training Aid to enhance quick learning
  • Safe environment for children
  • World-class classroom infrastructure for perfect programme delivery.

Learn Guitar

Learn Guitar – Information about types, parts and history

This article is first in the series to learn Guitar, as part of various Music Courses in Karama offered by Mindbuilder Training Center. It provides basic guitar information and introduces the beginners to the various parts of guitars and main types of guitars in general. In subsequent articles, we shall discuss, individual types of guitars in detail in terms of construction and playing.

Introduction to Guitar

A guitar is defined as a musical instrument with frets and with six strings in majority of the cases. Frets are the thin strips of metal located at intervals that are increments of half steps on scale of 12 tones. Frets are provided on the neck of the guitar and usually cover the full width of the neck. Board where frets are placed is known as the Fretboard or Fingerboard.

Parts of Guitars

You are required to use Both hands to play the guitar. With one hand you can pluck the strings by either with your finger or fingernails or by using what is known as guitar pick. At the same time, with the fingers of the other hand you have to press the strings against the frets, also known as fretting.

The three main parts of Guitar are body, neck and head. The strings get anchored or terminated to the body of the guitar at a part which is called as bridge. The sound produced by the vibrating strings is transferred by the bridge to guitar body and hollow chamber that results in the sound output of the instrument. This process is referred to as projection. In case of electric guitar, an amplifier and speaker is used for the process.

The guitar falls into a category of musical instruments known as chordophone where vibrating strings connected between fixed points and in stretched condition produce sound. Other examples being Banjo, Piano, Sitar Violin etc.

Brief History of Guitar

History of guitar can be traced back to about 4000 years ago. Following are the versions which preceded and were responsible for its development to present shape.

  • Gittern
  • Vihuela
  • Four course Renaissance Guitar
  • Five Course Baroque Guitar

Types of Guitars

There are three main types of guitars as shown below:

  • Classical guitars having nylon strings
  • Acoustic guitars with steel strings
  • Electric guitars having magnetic pickups

These three types have many variations. In addition to these main types, there are also other types such as bass guitars, resonator guitars, 12-string, Seven-string and eight-string

Guitars for different types of music.

The use of different type of guitars is also related to the type of music you like or want to play:

  • Classical, Flamenco or bossa novas – Nylon string guitar.
  • Folk or country picking – Steel string.
  • Jazz – Hollow body electric.
  • Rock & roll or blues – Solid body electric

It is usually recommended to start with is a nylon string guitar because it’s having the wider fingerboard with more room and its soft string allows you to learn to have a better string control.

Brief Description of main types of Guitars

The main features of different types of guitars is summarized below. The main types of guitars shall be dealt in detail on separate pages.

Classical Guitar – Also known as the Spanish Guitars.

  • Having Nylon strings, plucking done by fingers and played in sitting position
  • Used for variety of styles including classical
  • Has a wide and flat neck portion enabling you to play scales and certain forms without much interference form adjacent strings as compared to other forms of guitar.

Classical Guitar

Acoustic Guitars or Steel String Guitars

  • Steel strung to have bright and loud sound.
  • Most Common type is Flat top guitar and specialized versions are arch-top guitars and other variations.
  • Standard tuning is from low to high (E-A-D-G-B-E).
  • Use of different woods, different constructional elements such as type of bracing affect the tone of the instrument. Also, there are many variations in size, depth and proportions.
  • The larger the body, the louder the volume.

Acoustic Guitars

Electric Guitars

  • Required to be plugged into amplifier and has a metallic sound with a lengthier decay period.
  • Two types – Solid body guitars and archtop with hollow body.
  • No requirement of acoustic chamber, hence available in contoured and thin body designs.
  • Fender Stratocaster and the Gibson Les Paul are the two of the most popular designs.


Electric Guitars

Other types of Guitars

Bass Guitars

  • Hollow wooden body which is similar to acoustic 5 string guitar in construction but larger in size.
  • Has four strings that are generally tuned E-A-D-G.
  • In rare cases, comes with 5 or 6 strings to have wider range of notes with lesser up / down movement on the neck.


Bass Guitars

Resonator Guitars

  • All three types invented by John Dopyera. Purpose was to produce large sound. Hence largely superseded by Electric guitars, but still used due to its distinctive tones.
  • Appearance is similar to flattop guitar, but body can be made from brass, steel, nickel silver or even wood.
  • One of more Aluminium resonator cones are mounted to produce sound making the principle similar to loudspeaker.
  • Available as either round neck or square neck.


Resonator Guitars

Twelve string Guitar

  • Usually with steel strings.
  • Has wide usage in folk, blues and Rock & Roll.
  • Six courses are made up of two strings each similar to lute or mandolin. Highest two courses have to be tuned in unison while others in octaves.
  • Also made in electric form.

Twelve String Guitars

Eight String and Seven String Guitar

  • In 1980s and 1990s, seven string guitars with solid body became popular.
  • Some artists went a step further and used an eight string guitar which had two extra low strings.


Double Neck Guitars


Steel Guitars

Abacus Maths addition

Abacus Addition – How to do Abacus Addition

In the previous article, we had learnt about the use of Abacus, representation of numbers on Japanese Abacus, clearing the Abacus, working from left to right and complementary numbers. In this article, which is the first article on Abacus Maths, we shall have introduction to the procedure of carrying out abacus sums involving addition of single digit and multiple digit numbers. In subsequent articles we shall learn about subtraction, multiplication and division. Here, Abacus addition means carrying out addition operation by use of Abacus.

We shall see how to carry out addition problems for the following cases:

  • Case 1: Abacus addition of two single digit numbers whose sum is less than nine.
  • Case 2: Abacus addition of two single digit numbers whose sum is more than nine.
  • Case 3: Abacus Addition of two multiple digit numbers.

Case 1: Abacus addition of two single digit numbers whose sum is less than or equal to nine.

Let us do Abacus addition of 4 and 3, whose sum is 7, which is less than or equal to 9.

  • First, we shall set up the number 4 on Abacus by moving all the earth beads upwards towards the beam on the unit rod.
  • Now, in order to add 3, which is equal to 5 – 2, we shall move the heaven bead (in top row) down to add 5 and then move 2 earth beads down to subtract 2.
  • We now have heaven bead and 2 earth beads in set position giving us the result of the Abacus addition as 7.

Case 2: Abacus addition of two single digit numbers whose sum is more than nine.

Let us do Abacus addition of 4 and 8, whose sum is 12, which is greater than 9.

While doing Abacus sums involving addition of two single digit number whose sum is greater than nine, it is required to subtract the compliment of second number from the first number and one bead is moved up on the rod which is on the immediate left to the rod where addition is being carried out.

  • Set number 4 on the unit rod B.
  • Find the complement of second number with respect to 10, which is equal to 10 – 8 = 2
  • Now subtract 2 from 4 on the unit rod B by moving the last two earth beads downwards leaving only two earth beads in set position.
  • Move one earth bead upwards on the rod A (which is rod on immediate left of rod B)
  • Effectively the above operations can be explained as – We know that 4 + 8 =12, so if we replace 8 with 10 – 2, we get 4 + 10 – 2 = 12 or 4 – 2 + 10 = 12. In order to achieve 4 – 2, we carried out step 3 and to add 10 we carried out step 4 above.

Abacus Addition

Case 3: Abacus Addition of two multiple digit numbers.

Let us try the abacus addition of 21 + 6.

  • In order to carry out this abacus sums, we first set number 21 on the abacus frame by placing value of 2 on rod G and of 1 in rod H. Remember to enter this number from left to right with 1 being on unit rod.

Abacus Sums

  • In order to carry out addition from left to right, we are required to add 2 + 0 on rod G because number 6 can be considered to be equal to number 06.
  • Next, we are required to add 1 + 6 on the unit rod. The sum of these two numbers is less than or equal to 9, so we shall use Case 1 method explained above, whereby to add 6, we need to set the heaven bead by moving it downwards and move one earth bead upwards.
  • As can be seen, Rod G has value of 2 and rod H has a value of 7.

Abacus Maths

Let us now add 15 to the result of abacus addition of the above abacus sums, which is 27 + 15.

  • First, 23 shall carry out 2 + 1 on rod G, because we are required to work from left to right. We shall utilize method explained in Case 1, by moving one earth bead upward to place number 3 on the rod, because the sum of these two numbers is less than or equal to 9. At his stage the result is shown as 37, which is not the final answer but only an intermediate stage.
  • Next, we are required to carry out addition of 7 and 5. Since the sum is greater than 9, method in Case 2 shall be followed. We find complement of 5 with respect to 10, which is 5 itself. Subtract 5 from 7, by moving heaven bead up and we get answer as 2. At this intermediate stage abacus shall show 32.
  • Last step is to move one earth bead upwards on the rod G, which is rod on Immediate left to H.
  • By this operation, we get our final answer as 42 as shown on the abacus below.

Abacus Maths - addition of 2 two digit numbers

How to use an Abacus

Abacus Maths Training – How to use an abacus

Abacus has been in use for more than 5000 years in various forms. However, in today’s competitive world, where sometimes correctness of one extra question and fraction of second makes all the difference between success and failures, having all the required information about Abacus and learning how to use an abacus has become increasingly important. Mindbuilder training  provides Abacus classes in Dubai at its Karama Center in order to assist in achievement of above objective. This article provides the basic information about abacus and its use while subsequent articles deals with the basic operations such as addition, subtraction, multiplication and division operation through use of Abacus.

Difference between Suan-pan (Chinese Abacus) and Soroban (Japanese Abacus) were discussed in article about History of Abacus. All future articles about use of abacus shall be based on use of Japanese Soroban.

Essential Information about Abacus and its use

The Soroban abacus is best suited for a Base-10  numbering system. In Base-10 numbering system, each of the rod works as a placeholder and represents a value between 0 and 9.

In the Japanese Soroban with 1/4 configuration, in each of the rod, there is one bead above the beam called as the Heaven bead and four beads are below it, called as the Earth Beads. The Heaven Beads represents a value of 5 and each of the earth beads has a value of 1.

The value of any bead is ten times the value of the bead lying on its immediate right and one tenth of the value of the bead which lies to its immediate left.

If you carefully observe the beam, you’ll find a dot marking placed on the intersection of beam and rod on every third rod. The rods marked with such dots are called unit rod. Any one of such rods marked with dots can be designated to carry the unit number placeholder depending on the choice of the operator of the Abacus and his convenience.

However, it is usual practice to choose unit rod, just to the right of center on the soroban. Decimals are represented on the right side of the unit rod. If we are dealing with large numbers, we can choose the unit rod more on the right side and in case we are dealing with decimal numbers with larger number of significant digits we can choose it more towards the left side.

These dots also acts as markers by use of which, the larger numbers can be quickly and conveniently recognized.

How to use an Abacus

The beads are considered counted when they are moved towards the divider separating the upper and lower decks.

Setting numbers on an Abacus

While setting up numbers on an Abacus, you are advised to make use of only the thumb and your index fingers to manipulate the position of beads on the abacus. The thumb is used only to move the earth beads up toward the beam and all other type of movements are carried out by the use of the index finger ( such as moving all earth beads down and all heaven beads up & down).

In order to set numbers on the abacus, the operator slides the beads in upward or downward direction to make the beads touch the beam. Bringing up one earth bead and making it touch the beam gives the concerned rod a value of 1. If we move three earth beads up and make them touch the beam will give that particular rod a value of 3. To give a value of 5 to the rod, all the earth beads are cleared (moved away from the beam) and the heaven bead is moved downwards to touch the beam. Placing together one heaven bead and two earth beads will set a value of 7 and so on.

In Fig shown below from left to right, the numbers on single rods show 1, 3, 5, 7 & 9. Designating rod F as the unit rod, the soroban on the right shows the number 42,386 on rods B, C, D, E and F.

How to use an abacus

Clearing an Abacus

First operation to be carried out on abacus before using it is called as clearing the Abacus. To clear or empty the abacus, it is placed flat on the table or other surface in front of you. Then you are required to then tilt the frame toward you, whereby the gravity will pull all the beads down.

By this operation all the earth beads have been cleared and are away from the beam. Again, place the abacus back onto the table. Right index finger is used and moved in a sweeping motion from left to right between top of the beam and bottom of heaven beads forcing the heaven beads to move away from the beam. During this operation the abacus is held by the left hand. As a result of this action, none of the rods carry any value. What we get now, as a result of above operation is known as a Cleared Frame.

Clearing an Abacus

Two Important General Rules

We shall now study two general rules which are essential for quickly and easily solving any addition and subtraction problem with the Soroban abacus.

  • Always work from Left to Right: Fundamental to good Soroban technique is the rule always work from left to right. This is against the practice, we are accustomed to, while doing the pen and paper calculations, but is very important in using an abacus. It’s one of the Soroban’s biggest advantages. It allows us to solve mathematical problems with great agility and speed, in part, because numbers are added and subtracted in exactly the same way we read and hear them.
  • Finding Complement: Second, the Abacus operator must be familiar with how to find complementary numbers, specifically, always with respect to 10. The value or the number that should be added to the original number to make the result of addition as 10 is the number’s complement. For example, the complement of 7, with respect to 10, is 3 and the complement of 6, with respect to 10, is 4.

In competent hands, an abacus is a very powerful and efficient calculating tool. Much of its speed while calculating with abacus is result of use of mechanization, where we minimize mental work as much as possible and to perform the physical task of adding and subtracting beads mechanically, without thought or hesitation, which in a way leads to a  process of thoughtlessness.

Finding Complementary numbers is a technique to achieve above objective.
