What is the shell program to calculate addition of two numbers?

Hi,

I am learning the shell programming. I am aware about the c programming , but shell programming seems different than it. I need your help to code the shell program which will calculate the addition of the given two numbers. Another similar shell program will also work for me.
I would greatly appreciate your help.

Hi,

The programming logic behind the Shell programming and C programming is not is same, only there is difference in syntax. Below is the shell program which displays the addition of two numbers:

#!/bin/Bash

echo "Provide two numbers for addition:"

read a
read b

answer=$(($a+$b))

fi

echo $answer

Hi friend,

Please study carefully below shell program for addition:

#! /bin/sh

echo "Enter 1st number ="

read p

echo "Enter 2nd number="

read q

m="exp $p +$q"

echo "addition is =$m"

I have tried above shell program and it's executed successfully on my system. At the first time of execution of the above program I got some syntax error, But I solved that. I have also checked the output of the program and it was also correct.
Thanks to all.
