### Re: Peasant Multiplication

Yep, I think I know why this works. You simply convert the number to be halved into base 2, which is a sum of powers of 2. When you multiply by the other number, it’s equivalent to multiplying each term in the sum by the other number and adding up.

Q: Who wrote the novels Mrs Dalloway and To the Lighthouse?
