Assumed total? (3)
I believe the answer is:
sum
'total?' is the definition.
(I know that total can be written as sum)
'assumed' is the wordplay.
'SUM' is hidden in amongst the letters.
But, I am uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for sum that I've seen before include "Amount, aggregate" , "Whole" , "Total; problem" , "See 25" , "maths problem" .)
