Unlike many other books, I will not burden you with tons of exercises. Rather I will give you several tricks you can use right there. For some tricks, I will teach you method that you can calculate quickly. In computer science, those are called the “algorithm”. e.g. Trick 1 “Squares of number ended with 5” gives you an impressive party trick such that you can calculate the squares of two or even three digit number instantly.
