For those who are still struggling with mental arithmetic, or kids just learning, this seems like it would be a great way to practice --- there is a a certain addictive quality to it, like "flappy bird".

#82When I was near the end, I pressed backspace to clear my answer, and it wound up navigating me back to HN, wiping out my results. (I hate backspace-to-go-back. It's the worst feature in a browser. Is there a way to turn it off?) This mental math exercise is a cool and fun concept! Good execution.

#84After going for several minutes I gave up. In addition to a leader board, it needs to: - Have a time limit and see who can get the most calculations done on that fixed time - or, have a fixed number of calculations and see how fast people can answer them - or, it could get faster as you progress The calculation of the "you are better than X%" needs to be fixed because everybody in my office was better than 100%

#85Does it speed up or end eventually? I stored up 150 seconds left before I decided to quit (score of 2529).
For a moment I had the idea it was speeding up, but later on I felt like it was just an illusion. Got to 5661 before stopping.

#87For me there is a set of calculations I can do without thinking and there is a set where it takes several seconds to figure the solution out. No smooth transition. Is it the same for you? If yes, this would make tuning this game pretty hard because it is either to easy or to hard.
I noticed that with, for example, multiplication, I have a set of rote-learned answers for calculations that aren't 2, 5 or *10, and if the answer isn't one of those answers, I'll get the closest answer I can remember, and work back/forward from that. It's entirely habit, and I can't stop myself doing it. Algebra as well, I always have a moment where I swap parts of the equation in my head; even if it's utterly simple, there's still a noticeable cognitive step.

I love this feature. Makes browser navigation keyboard friendly.
Different strokes for different folks I guess.

They should remove that. It'll get them smacked by the google spam team eventually.
If not already... You really shouldn't do stuff like that. SEO 101.
It's even easier to do stuff the right way, especially in a one page design. Just leave the logic up above. Then put a long, well written text about math, the importance of brain exercise and a description of the game with well divided H1/H2 headings, below it. Here's all the SEO you need. The link from HN and all the sites that scrape it will do the rest.

#90People should start differentiating between mathematics and arithmetic.
