Christmaths—A Creative Problem Solving Math Book
About this ebook
Looking at topics linking Mathematics and Christmas—what the queen of the sciences and the king of the public holidays have in common—CHRISTmaths will not only appeal to a Christmas or Christian audience, but also to any problem solvers who enjoy mathematics recreationally.
CHRISTmaths should appeal to
• creative problem solvers who are bored by drill-and-kill math titles, and who desire to get an intellectual kick out of solving non-routine questions;
• mathletes who long for some creative mathematical problem solving to tickle their mathematical bones.
CHRISTmaths hopes to give readers the opportunity to experience the Ah, Aha! and Ha Ha of Mathematics.
