It is not an ordinary game that trains you how to solve the equations.
Here you should solve 5 equations. But you needn’t look for the final result. You should choose the right mathematical sign, “plus” or “minus” to solve the equation.
The exercises for the first level are quite easy, but then they become more and more difficult.
Those who study in the first form already know how to do such kind of a task. So, we hope they will help you cope with your homework.
We are looking forward for your comments. Could you tell us if more difficult tasks are needed?
