Their Story (source: their website)

We started LazyMaths.com, because we found many students struggling with Math problems that could be easily solved with simple shortcuts and techniques. We began by collecting well known as well as less known Math shortcuts and techniques that are simple and easy to use. Eventually, we built this website to share our collection. Even as you read this, we are continuously gathering more shortcuts and techniques to bring it to our user community.
