What is the value of -5 + 12?

Explanation:
Adding a negative number to a positive number works like moving along a number line. Start at -5 and move 12 steps to the right. After 5 steps you reach 0, then you have 7 more steps to go, ending at +7. Another way to see it is to subtract the smaller absolute value from the larger: 12 − 5 = 7, and the sign is the sign of the number with the larger magnitude, which is positive here. So the value is 7.
