2 + 2 + 2 = 6

3 group of twos are 6.

The total number of postcards is 6.

Example 2:

There are 4 group of bananas. Each group has 5 bananas.

5 + 5 + 5 + 5 = 20

4 group of fives are 20.

There are 20 bananas altogether.

Example 3:

There are 4 group of fours.

4 + 4 + 4 + 4 = 16

4 group of fours are 16.
