Cut times in A&E (3)
I believe the answer is:
axe
'cut' is the definition.
(I've seen this before)
'times in ae' is the wordplay.
'times' becomes 'x' (multiplication sign).
'in' indicates putting letters inside.
'x' going inside 'ae' is 'AXE'.
(Other definitions for axe that I've seen before include "Hack" , "Abandon project or cut back on resources" , "can bring down plane" , "Tool for chopping wood" , "Means of cutting" .)
