Write the numbers so that each place value is vertically aligned. Then subtract the digits in each place value. Work from right to left, starting with the ones place, and regrouping as needed.
114
Practice makes perfect
To subtract whole numbers, we first write them so that each place value is vertically aligned.
1 7& 7
- 6& 3
Next, we subtract the digits in each place value. We work from right to left, starting with the ones place, and regrouping as needed. If we need to borrow one from a zero, we first borrow from the following number. This way, the zero becomes a ten and allows us to borrow. Let's do it!
We found that the difference between 177 and 63 is 114.
