a='function of 'var1
b='function of 'var2
c='function of other vars' 
d='function of other script variables'
e='function of vars squared' 
f='other terms' 
g='more other terms'
h='more more other terms'

'var3='a'+'b'+'c'+'d'+'e'+'f'+'g'+'h

Keep your code human readable. In this case, longer isn't better. 
There is no continuation character; for best results, each line of your script should be under 512 characters long.
