18 (answer)
You have to use PEMDAS
[tex] Parentheses \\ Exponents \\ Multiplication \\ Division \\ Addition \\ Subtraction [/tex]
You have to do the division and multiplication first.
[tex] 3 \times 5 = 15 \\ 20 \div 4 = 5 [/tex]
The new equation is:
[tex] 8+15-5 [/tex]
First do the addition in the beginning:
[tex] 15 + 8 = 23 [/tex]
At last, subtract 5
[tex] 23 - 5 = 18 [/tex]
Your answer is 18
