I am trying to store an integer in x or y that gets returned as a string:

def add(a, b) puts "Adding #{a} + #{b}" a + b end def sub(a, b) puts "subtracting #{a} - #{b}" a - b end def mult(a, b) puts "multiplying #{a} * #{b}" a * b end def div(a, b) puts "dividing #{a} / #{b}" a / b end x = STDIN.gets.chomp y = STDIN.gets.chomp puts add(x,y)

The response that I get from the program is:

23 43 Adding 23 + 43 2343

    The problem is that gets ONLY returns a string. It has no concept of anything but a string, nor does the console, which gets reads from by default. It's up to you to make that value be something else. Commented Feb 7, 2014 at 4:22

Reset to default

Convert it to an integer with to_i:

x = gets.to_i y = gets.to_i puts add(x,y)

Note that there is no need to use STDIN.gets as long as you haven't passed any command line arguments, since gets reads from STDIN by default.
