Code secret

The tablet application offers for each referenced student the discovery of a secret in the form of:
- word (in uppercase script, lowercase script or lowercase cursive),
- number,
- result of an operation (addition, subtraction, multiplication or division)

Aids can be activated or not for each student:
- the letters / numbers can be displayed or not beforehand as you go,
- the letters / numbers can be pronounced or not to help the search,
- the keys with the letters / numbers are presented in alphabetical order or randomly mixed (in a different way for each child, so that a child passing after another does not identify the key by its position on the keyboard)
