TeachMe Simultaneous Equations

Have you ever wondered what Linear Simultaneous Equations (LSEs) are all about?

When you solve these equations, what does the solution mean? Did you know that these equations and straight line graphs are related? You might already know the equation of the straight line, y = mx + c (as seen in the TeachMe Linear Equations app). TeachMe Simultaneous Equations enables you to visualise graphically what happens when you change the values of a, b and k in a pair of LSEs in the form ax + by = k. In many cases the straight line graphs intersect - this point of intersection is important when considering linear simultaneous equations. But how? Sometimes they don’t intersect at all. In which case, how does this relate to the solution? These and other questions can be answered using this app.

The main features of the app are:
* An interactive approach to help deepen understanding of Linear Simultaneous Equations and how to find their solutions.
* Highlight where the point of intersection occurs.
* On-screen take-by-the-hand walkthrough to help highlight interesting mathematical features, including how to manually solve the equations.
* A Maths Calculator that provides comprehensive information relating to the simultaneous equations and their graphical interpretation, with the ability to solve manually entered equations.
