I'm feeling a bit 'num'bed by all these options. Maybe I should just calculate the result by hand to be sure.

I'm going with option B. It's the most straightforward way to convert the result to a number, and it doesn't require any extra parentheses.

Option A looks good to me. Using `Number()` around the entire expression ensures that the final result is a number, which is what the question is asking for.

I think option D is the correct answer. The `Number()` function is used to convert the result of the expression `(num + 10) / 3` to a number, which ensures that the result is evaluated correctly.
