it was quite easy

Ok, I’m completely lost on this. I try to add my code onto the script.rb and nothing happens. I click run and nothing. I can’t click next. Am I not doing it right or just don’t know how to use this website?


Try this:

sum = 13 + 379
product = 923 * 15
quotient = 13209 / 17

puts sum
puts product
puts quotient


In the first three lines you are defining the variables.
On the next three lines you are asking for the print of those variables - as the variables are math operations you get the result of the operations.

I hope I have helped.


In my attempt rather than setting up the 3 lines with the variables and the three lines with puts for each of the lines was all incorporated into one as per below.

puts sum = 13 + 379
puts product = 923 * 15
puts quotient = 13209 / 17

Would this be incorrect or could this cause more confusion once you are designing more complicated programs?

Is it standard to leave a blank line after variables?
