This demonstration does work well but development is still in progress.
The idea is that this can be used for introducing equations and their solution.
A possible sequence of practical investigations might be:
- 7 = 7
- 5 + 7 = 12
- 7 + 7 = 14 => 2 7 = 14 => 2 7 = 2 7
- 5 + x = 12 => 5 + x = 5 + 7 => x = 7
- 4 + 2x = 10 => 4 + 2x = 4 + 6 => 2x = 6 => x = 3
- ...
