The precedence of these operators *, / and % is the same and so they are evaluated from right to left in an expression 12 % 9 * 12 % 9 * 12 % 9 So, here 12%9 = 3 would be evaluated first giving us 3 * 12 % 9 * 12 % 9 Then, 3*12 = 36 is evaluated giving us 36%9 * 12 % 9 Then, 36%9 = 0 will be evaluated giving us 0 * 12 % 9 Then, 0*12 = 0 is evaluated giving us 0 % 9 Finally we have 0 % 9 which is 0.

Both % and * have the same precedence. In that case you must look for associativity, which is left to right in this case. So solve from left to right.
