From the seven-year-old mathematicians in the back seat, on the way to school this morning.

Son: What’s infinity plus infinity?
Other kid: Two-finity.
Son: Yep.
Other kid: What’s three-finity plus three-finity?
Son: Six-finity.
Other kid: Indeed. What’s one-finity plus another finity?
Son: Point one thousand five thousand ten thousand finity.
Other kid: How did you work that out?
Son: I got it from my experience.

I’d better check the school’s curriculum, just in case.
