f := lim a a 0 f + lim b 0 b f := lim a ( 0 a f ) + lim b ( b 0 f ) = ( lim b b 0 f + lim a 0 a f ) := f .
The convention
a b f := b a f ,
which this question is premised on, ensures that for each p , q , r R ,
p r f = p q f + q r f .
Alternatively, as suggested by GEdgar's above comment, we can simply adopt as convention
f := f .
