I'm unclear, rambling about figures (9)
I believe the answer is:
numerical
'i'm unclear rambling about figures' is the definition.
I can't judge whether this defines the answer.
'i'm unclear rambling' is the wordplay.
'rambling' is an anagram indicator.
'im'+'unclear'='imunclear'
'imunclear' with letters rearranged gives 'NUMERICAL'.
Can you help me to learn more?
(Other definitions for numerical that I've seen before include "like characters, perhaps" , "Relating to quantity" , "expressed in figures" , "Using arithmetic values" , "of digits" .)
