Answer 1

Hey dude! Here are some tips to maybe make it work.

1.CHANGE operation = gets INTO operation = gets.chomp

2. CHANGE number1 = gets INTO number1 = gets. to_f (do the same with your number2 variable)

Explantions:
1. the chomp method will remove "\n" (newline) part of the operation input which results into matching your case criterias and of coursw running your case codes.

2. The default data type that we get from using gets is i believe a String so what happened in your num1 + num2 is that the 2 variables where treated as Strings not Numbers. Example you input 1 and 2, the result will be 12 which is wrong because 1 + 2 = 3.

And the to_f method converts the input from String into a Fix number data type.
