Oriental grappling with zero on maths problem (4)
I believe the answer is:
sumo
'oriental grappling' is the definition.
'sumo' can be an answer for 'grappling' (I've seen this before). I am unsure of the 'oriental' bit.
'zero on maths problem' is the wordplay.
'zero' becomes 'O' (O resembles 0).
'on' says to put letters next to each other.
'maths problem' becomes 'sum' (a sum is an arithmetic problem).
'o' after 'sum' is 'SUMO'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for sumo that I've seen before include "Jap. wrestling" , "Traditional Japanese wrestling by fat men" , "Japanese wrestling sport of over-weight men" , "Kind of wrestling" , "foreign form of fighting" .)
