How to do two digit subtraction
For example, let’s take the problem: 25 - 17. Starting with the units, you can’t take 7 away from 5.
So, you have to regroup one of the tens in the 20 into a group of ten units. Then, you take away 7 from 15. The answer is 8. Finally, you check the tens side. You have one ten (2-1) minus one ten, which is zero. So, the final answer is 8.
