It’s no secret that I’m an opponent of calculators. In fact, I recently suggested to readers of 12Most.com that they burn their calculators!

### But there is one calculator that *isn’t* burn-worthy.

The QAMA Calculator requires the user to input a reasonable approximation before it churns out an exact answer.

So if you asked your QAMA Calculator to find the square root of 5, it would ask you first what $$\sqrt{5}$$ is really close to. Like this:

### That’s annoying!

Okay, maybe. If you need the calculator to do some quick work (the real reason to use a calculator), then you don’t need the darn thing quizzing you about an approximation.

### But then the kids will cheat!

Ah! You would think so. But check out what it does when you turn the feature off:

So what do you think? Will you get a QAMA Calculator? (It’s only about $25 after shipping & handling.) Will you let your kids use it?

*P.S. I paid full price for it – it’s not expensive and it’s a crazy brilliant idea, so I went for it.*
