SimulEquations is for teaching and learning of linear equations with two unknowns. Solutions by the elimination and substitution methods. Worked examples of solutions with each method shown side by side for easy comparison.

SimulEquations can generate hundreds of sums for practice, but users may also choose to key in their own equations.

Explanations provided for important steps in the solution to help understanding. The interactive guide can help the user do his homework if he keys in the sums. Marks automatically and can print a detailed report after each session.

Here are some key features of "SimulEquations":

Tutorial:
· Shows the two different methods of solving simultaneous equations - by elimination and substitution. Each method is clearly explained in a step by step manner. The elimination method of adding the equations vertically makes solving simultaneous equations fast and easy.

Practice:
· SimulEquations can generate hundreds of pairs of simultaneous equations for drills to ensure that the student masters the methods learnt. There are two levels of difficulty to choose from: average for beginners and challenging for advance learners. The student may also key in his own sums and let the guide help him solve them.

Worked Examples:
· There are many worked examples to provide help for students who have difficulty in doing the sums.

Reports:
· You can print out a report at the end of each practice session. The report shows each sum with its correct answer and the student's answer marked. It also includes the percentage score, the average time taken to do each sum and other details.

Special Features:
· A step by step interactive guide is provided to help the student solve the equations if he has difficulties. The guide does not solve the equations for the student but guides him along, providing feedback on his working for each step.
· A student can key in his own equations and let the guide help him solve it. This feature can help the student do his homework.
· Two players may compete with each other on one computer, reducing the number of computers required for a class by half. Each player can do the sums at his own pace.
