Question

Simplify the expression -9+7

Answer 1

Answer: -2

We have the number -9. Now what we need to do is add 7 to it. This would be the sequence

-9 (+0)
-8 (+1)
-7 (+2)
-6 (+3)
-5 (+4)
-4 (+5)
-3 (+6)
-2 (+7)

When I typed -2, you could see how that was when we finished adding 7. This means that this will be our final answer.

Hope this helps comment below for more questions :)

Answer 2

We have

-9 + 7 = -2

You can also rewrite this as

7 - 9 = -2

If it makes you more comfortable.

Hope this helps.
