Compute -12 + 7.

Explanation:
When you add a negative number and a positive number, you’re effectively combining their distances from zero and keeping the sign of the larger magnitude. Here, the numbers are 12 and 7 in magnitude, with the negative sign on 12. Subtract the smaller magnitude from the larger: 12 − 7 = 5. Since the negative magnitude is larger, the result is negative: -5. You can also picture starting at -12 on the number line and moving 7 steps to the right, landing at -5.
