Answer :
Answer:
-6
Explanation:
We can rewrite the expression as follow:
___ - ( - 2) = - 4
___ + 2 = - 4
Because two consecutive negative signs are equivalent to a positive sign.
So, we need to find a number that added to 2 is equal to -4.
This number is -6 because:
- 6 + 2 = - 4
Therefore, the missing number is -6
