Answer:
D. |-3 - (-10)|
Step-by-step 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
