Declare a class with functions

 Problem

Declare a new class with its own functions/methods, create a new instance and call its methods from the outside.

 Recipe

// Declare our new class

class mathClass {

    func add(a:Int, with:Int)->Int {
        return a+with;
    }
    
    func multiply(a:Int, with:Int)->Int {
        return a*with;
    }
}

// Create a new instance of the mathClass
let math = mathClass();

print(math.add(1, with:1));
print(math.multiply(2, with:5));
