Our activities during Mathematics Week focus attention on Mathematics and Mathematics Education with the aim of making Mathematics more interesting, attractive, relevant, challenging, rewarding and engaging to learners and the community at large, e.g. by highlighting the impact of Mathematics on our daily lives and stressing the importance of Mathematics as a foundation for careers in science, technology and managerial jobs. Mathematics Week is a vehicle to popularise Mathematics and to increase public awareness, understanding and appreciation of Mathematics.
Fundamentals of Mathematics is a work text that covers the traditional topics studied in a modern prealgebra course, as well as topics of estimation, elementary analytic geometry, and introductory algebra. It is intended for students who (1) have had a previous course in prealgebra, (2) wish to meet the prerequisite of a higher level course such as elementary algebra, and (3) need to review fundamental mathematical concepts and techniques. NOTE: This collection is a work in progress, and the content has not yet been marked up in CNXML. You can download PDF copies of individual chapters in from their respective modules.
This is another one of those cool math tricks that would be great to explore. It's a bit freaky, though, that the site doesn't actually ask you to type in any numbers.
Works the same way as yesterday's Regifting Robin
Two digit number is 10x+y so we have 10x+y-x-y = 9x, ie all results will be multiples of 9, the lowest 9 and the highest 81.
