She didn't like to practice multiplication?
That reminds me of the joke about how Noah gathered all pairs of animals onto the Ark, and after the floods ended, he told all the animals to multiply. The two adder snakes said we can't multiply, only add, so Noah asked God what to do. God told Noah to chop down some trees and make a table for the adders. Noah did as told, built a log table, and the adders multiplied happily.
