The use of single quotes prevents the values of $no1 and $no2 from being expanded. Furthermore, in order to actually capture output from a command, you have to execute it -- variable=value simply assigns value to variable, it's not executed as a command. What you want is variable=`command` with backticks (ASCII 96, not regular straight quotes) around the command you want to execute.
Code:
no3=`expr "$no1" + "$no2"`
It is against the rules to "bump" your own question, and actually reduces the likelihood that somebody will respond. It is extremely optimistic to expect a reply in less than one hour.
