With addition, you need to regroup in the event that there are more than 10 ones or 10 tens. In a subtraction, you must regroup whenever there are insufficient ones or tens to subtract.
When the lower digit is greater than the upper one.
please
You need to regroup when you have something like 46-39. You would cross out the 6 and make it a 16, because you are taking ten from the 4, then you cross out the 4 then make it a three, then you should get 7.
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!
l like adding better than subtraction in maths
