Assess, briefly, maths problem at college (3,2)
I believe the answer is:
'assess briefly maths' is the definition.
I can't judge whether this definition defines the answer.
'problem at college' is the wordplay.
'problem' becomes 'sum' (arithmetic problem).
'at college' becomes 'up' ('up' can mean at university).
Can you help me to learn more?
(Other definitions for sum up that I've seen before include "Recapitulate (as for jury)" , "(Of a judge) review the evidence" , "Money more than before" , "Provide a synopsis" , "Summarise" .)
