Answer 2

You have to use PEMDAS

`Parentheses \\ Exponents \\ Multiplication \\ Division \\ Addition \\ Subtraction`

You have to do the division and multiplication first.

`3 * 5 = 15 \\ 20 / 4 = 5`

The new equation is:

`8+15-5`

First do the addition in the beginning:

`15 + 8 = 23`

At last, subtract 5

`23 - 5 = 18`

Your answer is 18
