Evaluate each expression <br> 8-(-5)-3
Vesnalui [34]
<h3>Answer:</h3>

\large\boxed{10}

<h3>Step-by-step explanation:</h3>

In this question, we're evaluating the given expression.

The given expression is:

8-(-5)-3

We would simply solve the equation until we reach our final answer.

Solve:

8-(-5)-3\\\\\text{The "-(-" will turn to a plus sign}\,\,\\\\8+5-3\\\\\text{Add 8 and 5}\\\\13-3\\\\\text{Finish off by subtracting}\\\\10

A friendly reminder is when you see something like "-(-", you would turn it into a plus sign.

When you're done solving, you should get 10.

This means that 10 would be your final answer.
