(-4) + ____ = -12. The missing number is ________
- -5
- -6
- -7
- -8
Hint:
When you are asked to add two numbers of different sign, you subtract them and assign the sign of the largest number to the answer.
The correct answer is: -8
We are asked to find the missing number in (-4) + ____ = -12. Re arranging them, we have:
(-4) + ___= -12
(-4) + x =-12
x = -12 + 4
x = -8
Here, the numbers are of different sign, so we subtract them and assign the negative sign since 12 is greater than 4. Thus, the missing number is -8.
Hence, the correct option is d.
