| Mathler | Build an expression for a target | Mental calculation |

Estimation is its own skill
You can count a small, still group. A moving pile with overlap and depth is different. You have to judge its area, choose a reference group and correct for density.
Amountle gives you the exact count after every guess, so you can see whether you tend to estimate high or low.
