Question

Below are two expressions, the only difference being the presence or absence of parentheses. expression 1:expression 2:5+1×(3+3)×(5−2)5+1×3+3×5−2

Answer 1

Step-by-step explanation:

this is all about PEMDAS.

start with the parenthesis from left to right.

(3+3) = 6

(5-2) = 3

5+1x(6)x(3)x5+1x3+3x5-2

then do the multiplication from left to right.

5+90+3+15-2

then go from right to left and finish the equation.

95+18-2

113-2

= 111

final answer = 111
