Question

Is -7 + 9 equals -9 + 7 true false or open

Answer 1

False because the answer to the problems are different. One is positive and one is negative.

Answer 2

Hi!

The simplest way to find out if they're equal is by solving each of them.

Imagine a number line.

• -7 + 9

-7 moves to the right 9 times, and lands on 2.

• -9 + 7

-9 moves to the right 7 times, and lands on -2.

So, does -7 + 9 = -9 + 7?

Or we could say, does 2 = -2?

The answer is no. This is false.

Hope this helps! :)
