Casio FX-85DE CW

Scientific calculator with FULL DOT display and 310 functions
The innovative operation and menu-based navigation simplifies the use of the calculator for pupils. Shortcuts and key combinations are largely dispensed with. To this end, the functions have been expanded to include the "Maths Box" (for dice and coin tossing experiments). The maths box can be used to simulate dice and coin tossing experiments. The relative frequencies of the sums can be listed.
