Answer:
-7
Step-by-step explanation:
To add a positive number and a negative number follow these steps.
1. Ignore the signs and consider both numbers positive. You have 5 and 12.
2. Subtract the smaller number from the larger number. If the numbers are equal, subtract one number from the other. In this case, you have 12 - 5 = 7.
3. The sign of the answer is the same sign as the larger positive number's original sign. Here, the larger positive number is 12. 12 was originally -12, a negative number, so the final answer is negative. (5) + (-12) = -7
