What should Allison do next to find the value of the expression?

A. remove 2 negative tiles
B. remove 3 negative tiles
C. add 2 negative tiles
D. add 7 negative tiles

Answer 1

A. remove 2 negative tiles

Explanation:

-5 -(-2) is equal to -3. Two negatives make a positive, so this expression can be rewritten as -5 + 2.

To show this, you are "taking away" 2 tiles (-2) so the answer is to remove 2 negative tiles.

This corresponds with answer choice A. remove 2 negative tiles.

Answer 2

A. Remove 2 negative tiles.

Explanation:

The given expression is -5 - (-2).

Allison begins with 5 negative tiles.

The expression says, we have to subtract -2 from - 5

So we have to get rid of -2 from -5.

Therefore, from 5 negative tiles, we have to get out 2 negative tiles.

When out 2 negative tiles, we will have 3 negative tiles.

The answer is A. Remove 2 negative tiles.
