C (-3 - 10)
D (-3 - (-10)

Can you help please I have a test

Answer 1

D. |-3 - (-10)|

Explanation:

The answer is 7 because you move positive 7 if you go from -3 to -10, and

When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash leftover, and the answer is negative.

Therefore, |-3 - (-10)|

= | 7 |

= 7
