Pull a number backwards and forwards (6)
I believe the answer is:
onward
'forwards' is the definition.
(I know that forwards can be written as onward)
'pull a number backwards' is the wordplay.
'pull' becomes 'draw' (synonyms).
'a number' becomes 'no' (abbreviation).
'backwards' says the letters should be written backwards.
'draw'+'no'='drawno'
'drawno' written backwards gives 'ONWARD'.
'and' acts as a link.
(Other definitions for onward that I've seen before include "Advance like Christian soldiers" , "Direction to be taken by Christian soldiers?" , "Going on, advancing" , "Advanced" , "With advancing motion" .)
