Multiplication in Ruby

I am trying to multiple a variable (input from the user) and 4. For some reason, this simple task can not be completed by me.

Here is the code:

print "Enter an Integer between 1 and 12: "
x = gets
puts x * 4

Instead of multiplying x and 4, it will print x a total of four times.

That's because x is a string, and the * method on strings is repetition. You need to convert it to a number using the #to_i method first.

x = gets.to_i
puts x * 4

Should do what you want.
