oke.

 

I see it

 

I'm going for this  :

 

postivePower  :: Int -> Int -> Int 

PostivePower x 1 = 1 because when you multiply something by one is remains the same value.

PostivePower x y =  x + postivePower x y 

 

for example 

 

x = 4 

y = 3 

 

4 * 3 = 

4 + 4 * 2 

4 + 4 + 4 * 1 

4 + 4 + 4 

4 + 8 

12
