Question 4.

**Stretch Your Thinking** Write and solve a subtraction exercise where you do not ungroup. Write and solve a subtraction exercise where you must ungroup.

Answer:

Explanation:

In 84 – 32 = 52 we can group into tens and ones place

In 95 – 37 = 58 comes under ungroup

from smaller number 5 we can’t subtract the larger number 7.

So, we have to borrow 10 from tens place.
