MaMa

Randomly generate simple calculations and their solution. Renders them on console or as printable SVG, see example below:

Generate Random math problems for primary schools (Volksschule).

Type of calculation (plus, minus, multiplication, division) and many parameters concerning the random numbers and type of result can be configured in a json file. Example below produces :

• 3 multiplications with first number between 1000 and 99999 with no comma (moveComma)
• 3 division where the result has no comma (no remainder) "Integer"
• 3 division with any result (including periodic non-periodic rational numbers)
