Can you count to ten? Prove it!
The goal is to finish all 10 levels, writing the correct operations in the grid with numbers and operators available. Any complete operation disappears from the grid to make room for the following.
Each level takes place in 2 stages: the first is to write a number of correct operations in the grid (this number increasing over the levels); the second step is to complete all started operations to empty the grid.
Beware, numbers available evolve during levels. The first level provides only 0 and 1, the second 0, 1, 2, up to the 10th level which provides the numbers 0 to 10.
