Garble a calculation in maths class (7)
I believe the answer is:
algebra
'calculation in maths class' is the 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 can't see?
'garble a' is the wordplay.
'garble a' anagrams to 'ALGEBRA'.
But, I'm not clear how this is indicated.
Can you help me to learn more?
(Other definitions for algebra that I've seen before include "Branch of maths using letters and symbols" , "branch of learning" , "Maths with letters representing numbers" , "for study in class" , "Symbol-based branch of mathematics" .)
