This tutorial will demonstrate how to read from the input console (console line) to answer the prompts. The prompts will need to be a integer value to add the two inputs together.
The gets function is able to get a string from the console input, with the string inputted this allows the string function .to_i (to_integer) conversion for the answer to add up to integer values.
The code
---
print "Please enter number 1 : ";
# get the input from the console,
val1 = gets;
print "Please enter number 2 : ";
val2 = gets;
# convert the string console inputs to_i (to_integers) and add together
print "Answer : " , (val1.to_i + val2.to_i), "\n";

save that as addtwonumbers.rb.
To run ruby addtwonumbers.rb, and the output would be similar to
Please enter value 1 : 30
Please enter value 2: 23
