Bunny math

Our daughter is studying to become an elementary school teacher. She sent me a picture of the banner in her math book.

For the chapter on multiplication, the banner at the top of the page is a bunch of bunnies.

I don't get it -- what's the connection???

(Pssst ... Get your bunnies "fixed", so they can't do "math"!
It improves their mood, helps them live longer and makes them easier to litter box train!)
