Compute (−7) + 12.

Explanation:
When adding numbers with opposite signs, you subtract the smaller absolute value from the larger and keep the sign of the number with the larger absolute value. Here you have 12 and -7. Since 12 is larger in magnitude, compute 12 - 7 = 5 and take the positive sign. So the sum is +5. On a number line, starting at -7 and moving 12 units to the right lands at +5.
