The parenthesis in the second statement give precedence to 4 + 6 which are added first before multiplying by 9. The good news is that JavaScript works in the same way you use precedence in regular math. Try it out and enter both in the console. In addition to regular math, as you’ve...

Here, the multiplication has higher precedence than addition, so 4 * 3 is evaluated first, resulting in x = 10 + 12, which gives x = 22.To change the order, use parentheses:int x = (10 + 4) * 3; Now 10 + 4 is evaluated first, resulting in x = 14 * 3, which gives x = ...
