I wish to display to people that a number is a total. I have decided to use the greek symbol for sum:
Σ
Do I prefix or suffix numbers with this symbol?
Given the total is 10.
Σ10
or
10Σ

If $S_n$ is some sequence (for $n=a, a+1, a+2, \cdots, b-1, b$), its sum (total), $T$, is: $T=\sum_{n=a}^b S_n$
which is simply another way of saying
$T=S_a+S_{a+1}+\cdots + S_{b-1}+S_{b}$
Note also that $C \sum_{n=a}^b S_n=C(S_a+S_{a+1}+\cdots + S_{b-1}+S_{b})$
