Printing variables and strings

You've learned how to use and print variables and strings. But what if you wanted to print a phrase using variables and strings together?

In Ruby you can call a variable inside the string what you want to print.

To call the variable you neet to use #{variable}. For example:

number = 8
puts "I have #{number} oranges." # I have 8 oranges

You can even make math operations between variables inside it.

first_number = 5
second_number = 6

puts "Multiplying #{first_number} by #{second_number} the result is #{first_number * second_number}"
