Subtracting Two-Digit Numbers
Learning Objective
I can subtract two-digit numbers with regrouping.
Key Concepts
When subtracting two-digit numbers, it is important to line up the ones and tens places correctly.
If the ones place in the top number is smaller than the ones place in the bottom number, you need to regroup or borrow from the tens place.
When you regroup, you take 10 from the tens place and add it to the ones place so you can subtract.
