I feel like I've used infinitely approaching zero as a math joke before.

David

I feel like the equation in today's comic (Approach Zero) should be N*(x/2) instead of N+(x/2), where x is the amount charged per tutoring and N is the muber of tutoring sessions performed.

Otherwise each additional session is only adding one extra monies (assumedly to both of them as this looks set up to be an equal split, so they would both run the same equation) for each additional session.

I think this is actually that he already has N in his wallet

David

Ah, yeah that would work.

Anne

because he is talking about singular instance (another tutor) instead of a cumulative

Which would indeed be a N*()

David

It was really the wording then, the "another successful tutoring and another N+...", made it seem cumulative to me.
