What is Subtraction?
In simple terms, subtraction is calculating the difference between numbers. It is the most basic operation in math. The subtraction operator is denoted by the plus(-) sign.
How to perform Subtraction?
Subtraction is done using the following steps:
- Start with the units place – Subtract the bottom digit from the top digit in the rightmost column (units place).
- Borrow if needed – If the top digit is smaller than the bottom digit, borrow 1 from the next column (tens place). Reduce the digit in the tens place by 1 and add 10 to the current column.
- Move to the tens place – Subtract the digits in the tens place, including any adjustments from borrowing. If needed, borrow from the next column again.
- Repeat the process – Continue subtracting in the hundreds, thousands, and higher place values until all digits have been processed.
- Write the final result – Once all subtractions and borrowings are complete, the remaining number is the final difference.
This method ensures accurate subtraction, even when dealing with larger numbers.
