The application helps you to solve 3 popular kinds of
numeric riddles:

a) Pyramid :
The value c directly above 2 fields a and b in the line below is computed using
the formula c = a+b , c=a*b , c=a/b or c=a-b
(with fraction and decimal number support)

b) "Count the digits"
A popular question in TV quiz shows:
How often can you find a certain digit in a block of numbers ?
(e.g the digit 3 in the numbers between 0 and 99)

c) Sudoku
You can enter values from an external riddle or try to solve
2 built-in riddles.

Riddle types a) and c) can be solved step by step or completely in one step using
the [GO]/[go] button (with the same user-interface as realized in "Mathematics Tool").

Pinch and scroll support for all 3 riddles allows magnification of interesting areas,
easier entry of digits and the selection of a specific number-block for counting in
riddle type b)

application languages : English and German
(switched by horizontal scrolling of help-page)
