### 5/5 — High quality fractal shard to beat off the top math skills bubbling up piping hot and what not 🌡📛

High quality fractal shard to beat off the top math skills bubbling up piping hot and what not 🌡📛

Got the highest grade in my math class and I’m not even in school. Probably because I’m too cool for it thanks to an eBay pricing sister app that keeps me over icy cold chilling with the best deals. 

Changed my life for the better. Thanks to Crystal mathematics i stay hitting the math, weighing them numbers.   So dope!!❗️❗️🐦💬

### 5/5 — Gesucht und gefunden

*2018-11-19*

Erst einmal zum Aufbau der App, Sie finden in dieser App keine ,,Typischen“ Rechenformel, die Aufgaben sind als Textaufgaben aufgebaut (schematisches Beispiel: 46 Quersumme/10 mehr/weniger 5/zahlentauschen). 
Außerdem ist eine ausführliche Statistik enthalten, in der man seine Verbesserungen -als Tortendiagramm- übersichtlich sieht.

### 5/5 — Excellent game

*2018-10-26*

A very excellent game and really great pastime and good for maths wizards 

Good for 10 years and old kids

### 5/5 — Eine sinnvolle spaßige Spielerei

*2018-02-01*

Hab schon nach wenigen Tagen den Eindruck, dass ich deutlich besser geworden bin im Kopfrechnen 🤔💡. Wenn das so weitergeht, bin ich auch mal bester beim „Spiel des Tages“.

Tipp für Anfänger: erst mal eine Zeit lang mit „Freies Spiel“ üben.
