Answer:

regroup

Step-by-step explanation:

To use place value to exchange equal amounts when renaming a number is to regroup.

In regrouping you change groups of ones into tens to make adding or subtracting easier. For example you want to subtract 32 to 15:

 32

-

 15

------

Regrouping:

 2 (12)

-

  1  5

---------

  1   7

that is, 32 - 15 = 17
