Negate core learning in numbers (6)

I believe the answer is:

galore

I'm a little stuck... Click here to teach me more about this clue!

'negate core learning in numbers' is the definition.
I can't tell whether this defines the answer.

'negate core learning' is the wordplay.
'core' means to look at the middle letters.
'learning' becomes 'lore' (both can mean tradition or knowledge).
The centre of 'negate' is 'ga'.
'ga'+'lore'='GALORE'

Can you help me to learn more?

(Other definitions for galore that I've seen before include "Lots of" , "Pussy ---, Bond girl" , "Existing in great numbers" , "Aplenty" , "abundantly" .)

I've seen this clue in the Sydney Morning Herald.
