To evaluate, we use PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction


3 (6-3) -2^3 ... Start with the given expression


3 (3) -2^3 .. Deal with the parenthesis first: subtract 6-3 to get 3


3 (3) - 8 .. Cube 2 to get 8


9 - 8 .. Multiply 


1 ... Subtract


So 3 (6-3) -2^3 = 1
