We know that methods in Ruby can return values, and we ask a method to
return a value when we want to use it in another part of our program. What if we don’t put a
return statement in our method definition, though?

This means that if you have a Ruby method like this one:
def add(a,b) return a + b end
You can simply write:
def add(a,b) a + b end
And either way, when you call
add(1,1), you’ll get
Modify the code in the editor to use an implicit return.
