How to Review Subtraction - Out of the four basic arithmetic operations including addition, subtraction, multiplication, and division, the simplest are subtraction and addition. Not only is subtraction easy but it is very simple verify the answer that one gets. So, how do you proceed with subtraction? Consider an example 52-17: The first thing you have to do is write the sum down vertically. You need to understand that you always start from the right-hand side of the sum. Now, you see that 2 is less than 7 and you cannot subtract 7 from 2. What you can do is borrow from the digit on the left-hand side. You can borrow one from 5 and reduce it to 4. The 1 you borrow from the 5, will convert 2 into 12 and you can easily subtract 7 from 12. The final answer will be 35. Now you can easily verify your answer. You take the final answer and add it to the smaller number in the sum. The result will be equal to the larger number in the sum. This series of lessons and worksheets helps students learn to master subtraction skills.
