I dont know whay method is not working?

#IMC , Calculation of the corporal index of a person, then print it on the screen.
#We need to ask our costumer about the high(meters) and weight(kilograms)
puts "Hello , Welcome to Body mass index with ruby"
puts "Please write your first your weight in Kg , and them hight"
a=gets
b=gets
def imb(a,b)
  return a/(b**2)
end
puts imb(a,b)

Can someone help tell why the last line is not working?.(I put the numbers but nothing ,after it shows like there is a mistake...I dont get any result from the method imb example a=5 and b=41

You would have to convert the user input into integers like this:

a = gets.to_i
b = gets.to_i

On another note, are you sure this is how you calculate BMI?

Thanks Maciej

what happen if I have floats? , because the value of person hight can be 1.43m, the result may be floats too..

If you want floats use .to_f instead.
