See if one has a potato then he must by all laws of physics have a tomato. See rule 34 of EPICOSITY says for every one potato you MUST have two tomatos, but if you have half a potato then you will have 1 tomato. This is were it gets compicated see ∑∑x!=Potdet(A)4! = 1*2*3*4 = 24f (x)=3x, g(x)=x-1 ⇒(f ∘g)(x)=3(x-1) . Its quite simple, also last but not least π
