Long Subtraction Process:
Writing the Numbers: Start by writing two or more numbers one below the other, right-aligned. Make sure the place values (ones, tens, hundreds, etc.) are in the same column.
Subtracting the Digits: If the digit in the top number is greater than or equal to the digit in the bottom number, simply subtract. If the digit in the top number is less, you must borrow 1 from the next digit to the left. This means that 10 is added to the current digit, and 1 is subtracted from the next digit.
Writing the Result: Once all the digits have been subtracted, write the result below the line.
Example of long subtraction 523 and 278:
Subtraction of ones: 3 - 8. Since 3 is less than 8, borrow 1 from 2 (which becomes 1), add 10 to 3, which is 13. 13 - 8 = 5.
Subtraction of tens: 2 - 7 -1(borrow). 2 - 1(borrow) = 1. Since 1 is less than 7, borrow 1 from 5 (which becomes 4), add 10 to 1, which is 11. 11 - 7 = 4.
Subtraction of hundreds: 5 -1(borrow) - 2 = 2.
Calculation complete.
Long subtraction is a simple and efficient way to perform arithmetic operations. It is especially useful when working with large numbers or when you want to avoid making mistakes.
