For someone who is genuinely awful at all sorts of mathematics and calculations, the intellectually-stimulating QAMA calculator is a little intimidating. When I sit down with one of these devices, I need answers, and I need them now. Unfortunately for those hoping for an easy ride, this particular calculator only coughs up the answer when you’ve presented it with a reasonable estimate. If you’re close, then it’ll reveal its secret. If not, well, it’s back to the proverbial drawing board. That’s what we get for not studying, right?

The logic behind the calculator makes perfect sense. Instead of allowing students and the mathematically challenged to simply punch in number and reap the rewards, it forces you to use your brain. A foreign concept, I know. But it encourages people to actually learn about the equations they’re attempting to calculate, as opposed to simply allowing the tiny machine to do all of the hard work for you. Teachers will rejoice, students will weep.

How do you obtain one of these “revolutionary” calculators? Swing by the official website. Unfortunately, as of this writing, the site doesn’t seem to have any sort of ordering information available. If you’re curious to see the device in action, take a look at the video below.
