Thanks for replying DG
The question didn't ask for the change in temperature. Just asked 'how many drgrees is that'.
Would the answer be '5 dregees' or ' change of 5 degrees '
I asked an A level math student who said that the question was not worded clearly.
I agree with you that the question is poorly worded. But perhaps it's a 'verbal reasoning by the back door' sort of thing
With respect to the answer, since the units ('degrees') are already mentioned in the question, then just '5' should suffice, but it would be safer to put '5 degrees'. I assume that the idea is to fool candidates into putting '-5' degrees. If this is a paper you have to pay for, do you not get a mark scheme to go with it?
