Abacus and Vedic Maths  # Abacus Techniques for Quick Addition and Subtraction

Abacus techniques are highly effective for quick addition and subtraction. Here are some abacus techniques you can use to simplify these calculations:

To add numbers using the abacus, start placing the more significant digit on the abacus first. Then, move the beads corresponding to the smaller number toward the dots of the more substantial number. Count the number of beads that have been moved, giving you the sum.

### Carrying Over:

When adding numbers that result in a sum more significant than nine, you can carry over the excess to the next place value. For example, when adding 7 and 6, you move seven and six more beads to the next place value. If the number of beads moved exceeds nine, move the excess to the next place value while keeping the count on the current place value.

## Quick Subtraction Techniques:

### Simple Subtraction:

To subtract numbers using the abacus, start placing the more significant digit on the abacus. Then, move the beads corresponding to the smaller number away from those of the more substantial number. Count the total number of beads moved, which gives you the difference.

### Borrowing:

When subtracting numbers that require borrowing, start by borrowing the necessary number of beads from the next higher place value. Move those beads to the current place value, adjusting the count accordingly. Continue subtracting from each place value, borrowing as needed, until you obtain the final difference.

### Start from the Larger Number:

When using the abacus for addition or subtraction, starting with the more significant number is generally more straightforward. This reduces the need for borrowing or carrying over and simplifies the calculation process.

### Practice Mental Calculation:

As you become more proficient with the abacus, aim to mentally visualize and calculate the sums or differences while using the abacus as a physical representation. This helps develop mental calculation skills and speeds up the process.

### Regular Practice:

Consistent practice is critical to mastering abacus techniques for addition and subtraction. The more you practice, the more comfortable and efficient you will become with the abacus, leading to quicker calculations.

Remember, the abacus provides a visual and tactile representation of numbers and calculations, allowing for quick and accurate addition and subtraction. With practice, you can leverage abacus techniques to perform these operations swiftly and confidently.
