A factor in mathematics (8)
I believe the answer is:
multiple
This could be a double definition.
'a factor' is the first definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'mathematics' is the second definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe there's an association between them I don't understand?
'in' acts as a link.
Can you help me to learn more?
(Other definitions for multiple that I've seen before include "Several or many" , "Lit plume (anag)" , "Having or involving many parts" , "Involving or consisting of more than one" , "Numerous and often varied" .)
