First, follow PEMDAS (Parenthesis, Exponents (and roots), Multiplication, Division, Addition, Subtraction)
Also, follow the "left -> right" rule
-------------------------------------------------------------------------------------------------------
First, add 1 and 2 together
1 + 2 = 3
6/2(3)
Next, follow the left -> right rule, and divide 6 and 2 together
6/2 = 3
Finally, multiply 3 and 3
3 x 3 = 9
9 is your answer
hope this helps
