Add split to the chopped gets would work:

input_lines = gets.chop.split

a = input_lines[0].to_i

b = input_lines[1].to_i



puts a + b

Try it.

Check String doc.

More DRY way to do it:

input_lines = gets.chop.split.map(&:to_i)

a,b = input_lines



puts a + b

In this case the numbers inside input_lines already changed to Integers.
