How to answer 3•5+4-2•2+6-4

Question

I need help doing the steps to this problem. Also adding parenthesis, brackets, and braces.

Answer 1

Kelly, it's PEMDAS, parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right.

 

3•5+4-2•2+6-4

(3•5)+4-(2•2)+6-4

15+4-4+6-4

 

15+4=19

19-4=15

15+6=21

21-4=17
