Do you mean: \[\Large \frac{ \tan 35° − \tan 15°}{ 1 + \tan 35° \tan 15° }=~?~?\]

So, how would you find tan (35 deg-15deg)? That's tan 20 deg.

So then do I just plug it into the calculator?

^ That is pretty much the answer.

It just says to write the expression.

I'd suggest you not use the calc. in this case. As Steve stay, rewrite the given expression in the simplest form possible. See my previous comment.
