Use algebra tiles to find the difference. Let one white tile equal +1 and one black tile equal - 1.

Question

11 - (-5)
16
6
-16
20

Answer 1

To find the difference, we need to subtract -5 from 11.

Using algebra tiles, we can represent 11 as 11 white tiles and -5 as 5 black tiles.

11 white tiles - 5 black tiles = 16 white tiles.

Therefore, the difference between 11 and -5 is 16.
