alternatively you could make the two inputs variables and the output you are
trying to recieve a variable as well that way you would never have to worry
about regexing anything. You would simply reference the variable . . . You
can of course create a class as well . . .

puts "First Number"
r = gets.chomp
puts "Second Number"
p = gets.chomp
x = p * r
puts x

class Someclass
def initialize (First Number, Second Number)
@First Number = First Number
@Second Number = Second Number
end
end

Calc = Someclass.new(0,1)
x = calc.first * calc.last

Of course if you're working with floats or strings back and forth just add
the to_f or to_s. I haven't worked on ruby in a while but maybe this will
help you spawn some ideas.
