Please post what Operating System and version you have and what Shell you prefer.

Quote:
c=expr $n \* $m #value comes to -10 when echoed
As posted this does not execute the expr .
Did you mean:
Code:
c=`expr $n \* $m` #value comes to -10 when echoed

Or perhaps if you have a modern Shell:
Code:
c=$((n * m))
