Why it shows error

Question

puts "Put your mom\'s age"
x = gets
if x>18
puts "Your mom good :) "
else
puts "your mom gae"
end
#why error

Answer 1

Try doing
x = gets.chomp.to_i

Answer 2

If you put "Put your mom's age" it will not work as it will be picked up by Ruby as'Put your mom' instead of 'Put your mom\'s age'

Answer 3

In the 'x = gets.chomp.to_i' the 'to_i' asigns the input to a variable
