Confuse the figures (3)
I believe the answer is:
mix
'confuse' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for mix that I've seen before include "= 1,009 (L.)" , "Get on" , "Associate" , "Blend together" , "Blend or socialise" .)
