This is something a little different. South Africa has a decent amount of challenges around maths and science. I came across Microsoft Mathematics. A really nice free tool. You can download directly from here.

The short overview

Microsoft Mathematics provides a set of mathematical tools that help students get school work done quickly and easily. With Microsoft Mathematics, students can learn to solve equations step-by-step while gaining a better understanding of fundamental concepts in pre-algebra, algebra, trigonometry, physics, chemistry, and calculus.

Microsoft Mathematics includes a full-featured graphing calculator that’s designed to work just like a handheld calculator. Additional math tools help you evaluate triangles, convert from one system of units to another, and solve systems of equations.

That is a very nice tool to use! I specialize in the provision of private tutors and i recommend that students use this tool to assist them with their mathematics. check out http://www.brightsparkz.co.za
