This question already has an answer here:
I am wanting to write a little math training game that can run in the browser where users can do exercises with, addition, subtraction, division, multiplication, in a range from 0 - 100.
The exercises are in this form. 12 - __ = 8, or 5 x 6 = __ or __ / 4 = 3, where basically the result can be filled into the equation.
So I am looking for advice what language/framework and set up could be used and not really sure where to ask this. SO or Software Engineering or somewhere else?
