Question

What’s the answer to (-18)-(+6)=

Answer 1

The answer is -24

If you change the subtraction sign to a positive and then the positive six to a negative six, all you have to do is add 18+6 and take the sign of the larger number, which is negative.

So there you have it, -24

Answer 2

When you are adding and subtracting positives and negatives, it's a great idea to use a number line especially if you're new at it because it helps visualize what's going on. On a number line, zero is in the middle, all numbers to the right of zero are positive numbers and all numbers to the left of zero are negative numbers.

In this problem, I'll create a number line and attach it below.

-18 - 6 = -24
