So would it be more efficient to do a series of alphanumeric if comparisons to 
perform
100
-87
---
 13

Neither. Simple move statements will always require fewer cycles than
math. Too many programmers live in the belief that fewer code statements
result in better and faster code. Often the more mundane and less
"clever" methods are both faster for machines to process and easier to
maintain.
