Evaluate -7 + 12.

Explanation:
When adding a negative number to a positive number, you can think of it as subtracting the smaller absolute value from the larger one, and then keeping the sign of the number with the larger magnitude. Here, the positive 12 has the larger magnitude versus the negative 7, so you do 12 − 7 = 5, and the result is positive. On a number line, starting at −7 and moving 12 units to the right lands at +5, which matches the calculation. So the sum is 5.
