(25 + 35) / 2 * (4/2) please split this for me because when I compute using precedence rule I get 15.

The way I compute is step 1: (25 + 35) / 2 * (4/2) Step 2: 60 / 2 * 2 step 3: 60 / 4 step 4: 15 but the answer you provided to me is 60, how is it possible?

Hey Gundra Kiran,

The order of precedence is:

  1. Parentheses

  2. Multiplication, Divison, and Remainder

  3. Addition and Subtraction

Operators with the same priority will work from left to right. In this case:

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

(60) / 2 * (2) =

30 * 2 = 60

Good Luck!
