Subtraction With Regrouping

Subtraction is the process of taking one number away from another. It shows how much is left after something is taken away.

Regrouping in subtraction means to borrow from a higher place value when the top number is smaller than the bottom number in a column.

To subtract two-digit numbers, align the numbers by place value, subtract the ones place first, and then the tens place, regrouping if necessary.

A word problem is a math question written in words that requires you to use math to find the answer.

You can check your subtraction answer by adding the result to the number you subtracted to see if it equals the original number.
