Evaluate - 2 + 7 + (-4).

1

Step-by-step explanation:

You start by adding - 2 and 7.

Because the 2 is negative, it's like subtracting from 7.

This is how you get 5 from - 2 + 7.

Next, you have to add 5 and - 4.

It's like subtracting again, so you get 1.

The answer is 5

Step-by-step explanation:

-2 + 7 + = + 9
