Hello, so my question is why is it that the num argument is in parentheses when used in a return statement? Previous lessons taught me to use it as is (no parantheses). Is it because of + 3? if so why in parantheses? Please help me understand. Thanks!!! Your code so far

// Setup
let processed = 0;
function processArg(num) {
return (num + 3) / 5;
}
// Only change code below this line

Challenge: Basic JavaScript - Assignment with a Returned Value

This case is not related to return itself. Without parentheses - num + 3 / 5 - it would have different result, as the division would be calculated before num value is added.

It doesn’t need to be. Unless not adding parenthesis would cause wrong result. This might sound a bit vague, but the main factor is the operator precedence and what would be the intended result. With num added to 3 first and then divided by 5 - written as (num + 3) / 5; or 3 divided by 5 and then added to num - written as num + 3 / 5
