Question

13. 2 – (–8) + (–3) =

A. 1
B. 12
C. 7
D. 14

Answer 1

Hello!

The answer is: C. 7

Why?

To solve the problem, first, we need to consider the signs out and inside of the parenthesis.

We must remember the following rule:

`--=+\\+-=-`

We are given the following expression:

`2-(-8)+(-3)`

Then, we can rewrite it using the rule of the signs, we have:

`2--8+-3=2+8-3=2+8-3`

`2+8-3=10-3=7`

Hence, the correct option is C. 7.

Have a nice day!

Answer 2

C. 7

Step-by-step explanation

We want to evaluate

`2 - ( - 8) + ( - 3)`

We use the order of operations PEDMAS.

Dealing with the parenthesis first,we have

`2 - - 8+- 3`

Note that:

`- - = +`

and

`- + = -`

Our expression now becomes:

`2 + 8 - 3`

Next, we add to get:

`10 - 3`

We finally subtract to get,

`7`

The correct answer is C
