I need to flash numbers quickly, for addition training

September 23, 2016 12:19 PM

Is there a free or cheap program which displays sequences of random numbers and then, their sum? Screen-filling numbers, like Sesame Street. One, two, three and even four digits, positive and negative. Repeatable sequences and user-controlled speed a plus.

And the refresh rate must be less than one second.

Sounds like the kind of thing that should be super easy to throw together in Javascript on a web page. Can you provide some example sequences?

 211
 367
 112
-468
  56
... each number filling the screen, flipping to the next in less than a second, and at the end, after a longer interval the solution appears:
278

I've done it with Powerpoint but there's gotta be an easier way.

Honestly, given how specific your requirements are I'd suggest programming it yourself. It would be very quick to do in Processing or Python or JavaScript, as suggested above. I doubt there is a quicker way to get exactly what you're looking for, as addition trainers are mostly for two numbers. Good luck!

I'm on my way, getting some good results after playing around with it for a while, thanks for the pointer! I'd never heard of Processing^* before but it seems to be exactly the tool I need. Thanks!
