Passing arguments interactively to script

Question

How can I echo questions to the Terminal, and pass the answers to the same script?

The steps would be:

A script that output the questions - one question after the other where I can add the answers after the :.

Example:

Number 1: 2

Number 2: 4

Number 3: 6
A way to pass the arguments given in step 1 to the script and calculate the sum.

The final output would be: 12.

You might want to look at expect for how to pass arguments, or have a script that can take the values in other ways like command line arguments — Eric Renouf

Is this what you had in mind?

#!/bin/bash
read -p "Number 1: " N1
read -p "Number 2: " N2
read -p "Number 3: " N3
echo "Sum: $((N1 + N2 + N3))"
