JavaScript math operations have the same precedence as normal math operations. That is, multiplication and division are done first, addition and subtraction then.
In the following example, 2
is first
multiplied by 2
, and then 3
is added to the result:
let a = 2 * 2 + 3;
alert(a); // shows 7 (the result of 4 + 3)
Determine what will be displayed on the screen without running the code:
let a = 5 + 5 * 3;
alert(a);
Determine what will be displayed on the screen without running the code:
let a = 5 + 5 * 3 + 3;
alert(a);
Determine what will be displayed on the screen without running the code:
let a = 8 / 2 + 2;
alert(a);
Determine what will be displayed on the screen without running the code:
let a = 8 + 2 / 2;
alert(a);
