Get the total to make sense? (3,2)

Ross

I believe the answer is:

add up

I'm a little stuck... Click here to teach me more about this clue!

'make sense?' is the definition.
('add up' can be a synonym of 'make sense')

'get the total' is the wordplay.
I cannot really understand how this works, but
'total' could be 'add' (synonyms) and 'add' is found within the answer.
The remaining letters 'up' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'to' acts as a link.

Can you help me to learn more?

(Other definitions for add up that I've seen before include "Sum - make sense" , "tot" , "Put together (numbers)" , "Do sums" , "Make sense; count" .)
