Where do parentheses go in my 2 equation s

Question

80-36 / 2 + 6 - 2 x 5 + 1 = 44 ?

3 x 5 + 4 - 2 x 2 + 6 - 4 = 15. ?

Answer 1

The parentheses could go anywhere. However, assuming you mean for the parentheses to satisfy the order of operations (PEMDAS) then is would be thusly...

80-36 / 2 + 6 - 2 x 5 + 1 = 44

turns into...

80 - (36 / 2) + 6 - (2 x 5) + 1 = 44

...and...

3 x 5 + 4 - 2 x 2 + 6 - 4 = 15

turns into...

( 3 x 5 ) + 4 - ( 2 x 2 ) + 6 - 4 = 15
