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
