Obtain QAMA

The Inventor of QAMA

Living off inventing is a nearly impossible but extremely rewarding career.

Physicist ILAN SAMSON is doing just that – serially inventing products which people  really  need, and thus many millions of them use. Further information may be found at

One of his hardest but most important challenges was the well known ‘calculator problem’ - The constant usage of calculators seriously subverting against the understanding of arithmetic and math.

The resulting situation is particularly serious as our subsistence increasingly relies on advanced science-based technology which, without a firm grounding in math, is like Opera without music.

From his previous work in developing ground-breaking math-education tools (Demathtifying – Demystifying Mathematics  QED/Tarquin Books/Amazon), Ilan knew that, with suitable teaching means, people could in fact get a lot better at math than they ever dreamt, do so rapidly, and enjoy it too.

However, the performance of all quantitative work without the engagement of the brain is a non-starter for learning math.

So, a new, imaginative calculator had to be thought up, and this is how the QAMA calculator came about - a calculator that reveals the result only after the user has also entered a mental estimate of the result – just good enough to convince the calculator that he and she understood what they were dealing with.

As with every successful invention, an idea is not enough: It is the details that matter, and here it was the nearly insurmountable task of devising algorithms that prepare a reasonable acceptance-tolerance for any calculation whatsoever, namely, tolerances that must reflect the difficulty or ease of the task, so that the user would invariably find that estimates which they regarded as reasonable, would indeed be accepted, while wild guesses be rejected. With infinitely many calculation types and combinations, it was not clear from the start that this could be achieved at all…
