Is there a way to make variables always precede numbers in output with sums (but not multiplication)? For example, in writing arithmetic on subscripts I always willl write, say a_(n-1) Mathematica of course alwasy takes that input, and turns the sum around in the output a_(-1+n) Is there a way to keep the output the way most people would write such expressions on paper?
