WebA complete explanation of precedence can get complicated, but just to get you started: Multiplication and division happen before addition and subtraction. So 2 * 3-1 yields 5, not 4, and 2 / 3-1 yields -1, not 1 (remember that in integer division 2/3 is 0). If the operators have the same precedence they are evaluated from left to right.
