Math geeks who are also game geeks will love this calculator. It won’t help you with your Killzone game, but maybe you can figure your kill/death ratio with it. It is called the Cool Gamer Calculator, and yes it is a calculator in a shell that’s shaped like a video game controller.

It gives you all of the basics like add, subtract, divide, multiply, memory, percentage and square root. The Cool Gamer Calculator is available for $13.99. It’s the best of both worlds in one cool gadget.

At last a green solution to all of those calculators that run on gas. Think about it. No more carbon monoxide fatalities during math class. No more having to take your calculator to the mechanic to get an emmisions check. At last, we can cleanly crunch numbers.

So I exaggerated a little. This water powered calculator is still cool. It uses three water batteries for power which have two electrodes inside made from a special alloy. When immersed in water they produce electricity through a chemical reaction.

You know how it is. You’ve sold a ton of dope or just unloaded a huge shipment of guns, or maybe you’re just a millionaire who doesn’t trust banks and you keep your cash piled high in a secret room. You need to count all of those greenbacks.

Use this Multi-Cash counter & counterfeit detector for counting your multiple currencies. It comes with an onboard OLED count display and a detachable LCD display for customers, and built in UV, Metal and Thread detection for added security.

Calculators just aren’t cool. They have long been associated with nerds that wear taped-up glasses and pocket protectors. Well, this calculator should help you nerds up your game a bit since it looks like a video game controller. All of the buttons are in the right place.

This calculator has 27 functions, an 8 digit LCD display, and a two handed design. It won’t kill zombies, or cure geek acne, but it will kill math problems dead and make homework faster.

The 10 key calculator doesn’t know what it wants to be. It’s a calculator, but it has computer keys. When you put computer keys on a calculator, it gets bulky and the dork factor goes up dramatically.

If this is your kind of calulator, it’s also USB enabled so you can use it with a computer just like a standard numeric keypad….Which you probably already have. Unplug it from your PC and it’s a regular calculator again.

Calculators come in all shapes and sizes these days. One of the geekiest and neatest may just be this Lego calculator. It could help you count all of the Lego pieces that you have stored in that dumpster next to the garage or count how many bricks it will take to make a cool statue.

This one comes in four colors, red, blue, green and black. Not sure if you can actually connect your Lego pieces to this though and get creative. The building block calculator will be available in August, but you can pre-order it now for $27.

Are you a fan of Texas Instruments’ graphing calculators? Well, now the TI-83+SE, TI-84+ and TI-84+SE calculators can do more than make calculations. Now they can play Nintendo Game Boy games thanks to Brendan Fletcher’s emulator known as TI-Boy SE.

It runs on TI’s Z-80 based graphing calculators thanks to similarities between the CPUs of the two systems. The emulator includes three zoom modes, two sprite tracking modes, grayscale or black-and-white palettes, two-channel sound and even the ability to save and load games. For now, only Tetris, Zelda: Link’s Awakening and Kirby and homebrew titles are supported, but I’m sure it will get better.

Numbers are an enemy to all. They force us to do endless calculations throughout our daily lives, and miscalculations. Numbers are everywhere. You can’t avoid them. By the time you have begun counting, they have already won. Because there will always a higher number then you can count.

Calculators are our only hope of staying sane as we constantly wage war with math. This one is slim yet stylish and solar-powered. And Credit Card sized. Having one the size and shape of a standard credit card will go a long way in helping you sort out this mathematical universe. No more miscalculating! Only $6.

I still can’t figure out why the calculator is making a comeback, but here’s yet another example of a new twist on the number crunching device. If the HP Quick calc isn’t enough or the keyboard calculator is too expensive, this USB Hub calculator has the added benefit of being a bit more useful.

Aside from the hub aspect, with 3 USB ports, it also has some other bonus features, like a 12/24 hour world clock with alarm, a calendar and a even a thermometer. And it’s only $19, so it won’t kill you in the wallet. If you absolutely need a calculator, it might as well have a few other functions.

Seems like calculators are making a comeback, though why, I have no idea. Maybe it has something to do with the calculator in your computer and cellphone no longer working in a Mad-Max type future, after a burst of Gamma radiation hits the planet or something…

At any rate, HP wants you to be prepared, going so far as to offer a variety of colors. They’re small enough to fit on a keychain too, so if you have to battle zombies you won’t lose it. Thank God for HP. You’ll be the only survivor who can do math.

Most devices already have a calculator app built in, including your computer. That’s why most people have no use for a stand-alone calculator. But if you do want or need a number cruncher that’s free and untethered and all independent like, this is the one to get. The 10-key calculator. It’s what a calculator would have looked like if there had been one built into your keyboard number pad. Instead of soft squishy keys, you get the clickety clack of a keyboard, which I’m sure won’t help it fit in your pocket and it will only annoy fellow nerds. All of this backwards innovation will cost you $88. Oddly, it’s only available in red or white.

First off, a USB calculator is pretty useless. I mean wth, are you too lazy to use the calculator app? Maybe it’s for our parents and grandparents who may not be able to find it. Plus, everything has a calculator built in these days.

At any rate, stupid as it is, this one can be forgiven, because it also works as a 4 port USB hub. It’s available in hot pink(For those who want the color without the Kitty), white, or black. For $16.00 the USB Calculator Hub is an affordable gift for those who may not be able to find calculator app on their own.

People use calculators less and less these days thanks to the function being built into other devices like cell phones etc. But if you are the rare scientific nerd or number cruncher who still needs one, why not calculate in style with a sort of Cadillac of calculators.

The Jet Calculator from LEXON should appeal to design-minded consumers who need a standalone model. It’s made from aluminum alloy and comes in silver or gold finish. The sliding screen is fairly useless and it still has plastic keys with a generic LCD…Not exactly the cadillac of calculating after all, but it does have a certain style. They will be available in Korea in April for about $42 and $53.

Geeks love robots, despite the fact that they will one day destroy us all in a fiery Armageddon. Some geeks also love calculators. Combine the two and you’ve got any early geek christmas. These calculators are designed to look like older style robots and they have alot of personality.

They have a magnet that can hold paper clips, the can hold notes and they have movable hands and feet. They even sport a detachable push button night light. Oh yeah, did I mention that they are also calculators? You can get them in three colors: white, blue and lime green. The price is $14.95. What are you waiting for? Go get one!

I’m not sure what the thinking is behind this water powered calculator. As far as I know, no one is having any difficulty with their solar powered calculators and the sun hasn’t burned out as far as I can tell. I suppose it might come in handy for 2 lone researchers facing 6 months of night in a polar bunker though. So this one’s for you guys. Hope you’re reading.

To get this calculator to work just pour water into it and insert a stopper. The electrolytes in the water power it so you can crunch your numbers. It only costs $8.99. How you are going to get it shipped to your end of the world location is your problem.
