## What does Regroup Mean?

**In math, regrouping can be defined as the process of making groups of tens when carrying out operations like addition and subtraction with two-digit numbers or larger.** 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.

We use regrouping in addition when the sum of two digits in the place value column is greater than nine.
