(35+25)/2*(4/2)

First the parentheses are evaluated giving 60/2*2 Everything else is left to right so 60 divided by 2 equals 30. 30 times 2 is equal to 60. This is because multiplication and division have the same priority or precedence. In such a case, we evaluate left to right.

(35+25)/2*(4/2): order of operations says do 35+25 to get 60, then divide by 2 to get 30, then multiply by 2 to get 60
