Answer: 40
Explanation:
For this problem, you need to know the properties of multiplying negative numbers.
- × - = + [negative×negative=positive]
- × + = - [negative×positive=negative]
+ × - = - [positive×negative=negative]
+ × + = + [positive×positive=positive]
Now that we have established the different sign changes, we can multiply -8 and -5. Multiplying -8 and -5 would be the first option. We know that our answer would be positive.
(-8)(-5)=40
