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!

To regroup means to rearrange groups in place value to carry out an operation. We use regrouping in subtraction, when digits in the minuend are smaller than the digits in the same place in the subtrahend. Here's how we regroup hundred and tens to subtract 182 from 427.
