Standard subtraction with regrouping

In addition to practicing basic math facts, students need to understand the different methods that can be used to solve problems. This blog post will provide step-by-step instructions for solving two-digit subtraction problems with regrouping. By following these steps, parents can help their children develop a deeper understanding of this concept and become more confident in their math skills.

To subtract two-digit numbers with regrouping, follow these steps:

1) Line up the numbers on two lines so the one's digits are directly below each other and the tens digits are directly below each other. For example, if you were subtracting 27 from 35, it would look like this:

  35

 -27

2) To subtract the ones digits, simply subtract as you would normally. In the example above, this would give you 5-7. Write this answer in the ones column of your new number line. The example now looks like this:

  3  5

 -2  7

3) Now, we first need to regroup or borrow. This means we take 10 from the top and add it to the 5. Then, we write 15 under 7 like:

  2  15

 -2    7

   0    8

Answer = 8

  5    <-- We "borrowed" a ten, so now we're subtracting 27 from 35, which gives us 8! Don't forget to carry down your final answer when you're done!
