Invoking a Method

Ruby
1

Hi,
Newbie Question:

How do i invoke a method in belonging to a module?

For Example:
###############
#file: SampleModule.rb

Module SampleModule

def add(a, b)
return a + b
end

def multiply(a, b)
return a * b
end

end

################
#file: test.rb

require ‘SampleModule.rb’
#here i would like to make a call to add() method of Module SampleModule
(sitting in file: SampleModule.rb)
help??

this seems to work:
SampleModule::add(2, 3)
so i think i’m ok for now.

Thanks.

SampleModule.add(1, 2)

add this lile:
include “SampleModule”

then you can use the add, multiply normally.
