Problem Solution:

In this program, we will create a module and create variables. Then we will define methods inside the module. After that, we will call methods defined inside the module.

Program/Source Code:

The source code to create a module with variables is given below. The given program is compiled and executed successfully.

# Ruby program to create a 
# module with variables

module MyModule
    Num1=20;
    Num2=10;
    
    def MyModule.MethodAdd
        print "Addition is: ",Num1+Num2,"\n";
    end
    
    def MyModule.MethodSub
        print "Subtraction is: ",Num1-Num2,"\n";
    end
end

MyModule.MethodAdd();
MyModule.MethodSub();

Output:

Addition is: 30
Subtraction is: 10

Explanation:

In the above program, we created a module MyModule with 2 variables Num1, Num2 initialized with 20, 10 respectively. Then we defined 2 methods MethodAdd, MethodSub inside the created module. After that, we called all defined methods and printed the result.
