On Debian (and, I'm sure other distributions of GNU/Linux) the 'bsdgames' package contains a simple program called 'arithmetic' which poses similar challenges, albeit reduced to the most elementary operations: addition and substraction. Call as

    arithmetic  -o '+-x/'
in order to add multiplication and division.

I find it a handy supplement to 'gtypist' in order to train touch-typing of numbers.

On a side-note: I'm surprised at how scarce such software is - pitiful as it may be. But then, the advancement of the human intellect isn't at the forefront of our cultural conscious, is it?

Noticed some fun SEO hacking at the bottom of the page: puzzles calculate formula mathematics maths decimal number calculating mathematician multiply measurement probability equation division measure homework units word problem solve converting resources tessellation anxiety math problem problems convert unit ratio number trigonometry perimeter divide mental multiplication calculus math quadratic triangle teselation…

They should remove that. It'll get them smacked by the google spam team eventually.

Wow it's early 2000's style of SEO - lots of individual words rather than actual searched-for phrases.

Good game, it has that silly 'flappy bird' style appeal that it is difficult to keep going - they should reduce the additional time given per question to go more in that direction.

For 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.

Could Google theoretically calculate the probability that some text on a webpage is extremely hard or impossible for humans to readily see based on info from the source page about the background and text?

Not just theoretically. Very concretely.

Well I said probability because depending on how complex the background is such as photographs, video, or some weird scrolling behavior, there could be some hindrances to having a computer accurately or computationally-efficiently determine this.

Google uses filters, which run in different intervals apart from the main algorithm and have different effects for a page or the whole website. This is why spammy SEO tactics often "work for a while" - until said computationally intensive filter catches them and often punishes the whole website. Prominent examples for these filters are Panda [0] and Penguin [1].

https://github.com/michaeljakob/10-seconds-math you can submit a PR to remove it

This SEO spam is not in the Github repository. It seems Michael Jakob knows full well that it is frowned upon.
