What regroup mean in subtraction?
Regrouping in subtraction means that if you can't subtract because the digit on the bottom has a greater value than the digit on the top (such as 3-6), you have to "regroup" and subtract on from the top digit to the left of the digits your working with and then add a ten to the top digit your working with. Finally, you subtract. (645-9=630+15-9) Hope that makes sense!
