Answer 2

You have to use PEMDAS

$Parentheses \\ Exponents \\ Multiplication \\ Division \\ Addition \\ Subtraction$

You have to do the division and multiplication first.

$3 \times 5 = 15 \\ 20 \div 4 = 5$

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
