#72Too bad it's things like this that make average people think math is little more than arithmetic.
Re: Ten seconds of math
#73This is pretty cool but, is it a game? I can't see how solving math problems under a time limit can be useful for anything besides a math exam or some other academic test.
My experience has been that mental math training, while not directly useful, generally seems to improve the way my brain works and enhances my analytic thinking. This effect is a lot more tangible with longer, multi-step problems. In college (physics major) I made a point of doing every integral in my head if I could, and over time I found that my mental 'scratch space' seemed to be getting longer - that I could hold…
General problem solving and critical thinking is good mental training. Timed arithmetic drills are neither, and I really should hope that arithmetic doesn't count as "critical thinking" for the majority of the audience on HN.

#74I actually made a mental math game for Android not long ago. The concept is different though - it's about choosing the operations to reach a target number. I would appreciate any feedback! https://play.google.com/store/apps/details?id=com.woodenclos...
I have this on my phone, my 5 and 9 year olds like it!
I find the hard level pretty hard - it would be good IMO if you could change the mode to include negatives (maybe roots and squares [+other powers?], like here) and to expand the number range to. I seem to remember someone mentioning (probably on here) that they played a mental maths game where you had to give an operation on a number, you didn't say the answer but the next person had to add an operation, there was always a range (age adjusted) that the answer had to fit within: was that game the inspiration or was it just a novel idea for you?
Like the game anyway, thanks.

#75For me there are certain mental calculations that take longer to process than others. 2 + 2 is super easy. 7+8 is not as immediate. I need a program like this that learns which calculation take me longer, even if it's just slightly longer, and then drills and drills my weak points over and over again. That would be a real mental math trainer.
With a bit of tweaking, Anki [0] or another Spaced Repetition Software program will do just that. You can configure it to categorize your answers by how fast you answered them. Then it will make the easy ones less frequent. I used it to memorize the times table up to 20x20. [0] http://ankisrs.net
Is that stack available for times-tables ready to install and use, if not can you share it? Thanks.

#76I thought that maybe the ranking was real.. no its not function getRank(score) { // TODO we should add a real ranking one day var ONE_BARELY_REACHES_THIS_SCORE = 200; return Math.floor(100 * Math.min(Math.E * score / (ONE_BARELY_REACHES_THIS_SCORE * Math.PI), 1)); }
WTH?? then why release it in the first place.. That's the only crucial step in this whole concept..

#77Square roots should be improved, just ranges from squares of 0 to 6.

#78OT: I ended up being mostly fascinated with the FB and Twitter share buttons
Why? I can't see anything interesting about them, they seem stock?

I'll quote one of my math professors: "At this level, nobody knows how to subtract!"
