Calculator Reviews

I wish I could take credit for the amazing video that follows, but I can’t, so I just want to share it with everyone that follows Tech Powered Math. It’s from the YouTube channel TanRu Nomad, a great channel I’ve been subbed to for a while that covers retro games and computers. The video shows off a Friden EC 130 Calculator, the world’s first solid state calculator. There’s nothing I can say that can better explain or build on this video, so please watch and enjoy.

Looking to buy a TI-92 Plus? I recommend you find the best selection on a TI-92 on Ebay. When I started coaching our math team in 2007, I was shocked to find I’d inherited a closet full of TI-92’s just collecting dust. They were all in perfect working order despite being a decade old. Since it turned out they were allowed in our competitions, we set to work upgrading the operating systems, loading up apps, and training the kids on them.

For a great selection of used graphing calculators, click here to see Ebay’s full selection. While most end up buying a new calculator, some thrifty students (or their parents) end up buying a used graphing calculator. Much like buying a used car, the main advantage is depreciation. You can often buy a used graphing calculator for half of what a new one would cost. On the other hand, much like buying a used car, there are some risks.

I’ve been watching the top 20 graphing calculator rankings on Amazon for a while now. What’s that? You’ve never spent time following the “power rankings?” Let me tell you. You’ve been missing out. It’s not the story you might think you’ve been missing out on: The TI-84 Plus has had a stranglehold on the top spot for years as the various iterations of the TI-Nspire have slowly climbed the ladder trying to knock it off.

Click here to buy your HP 50G on Amazon . HP graphing calculators haven’t had the highest profile the last few years, but that’s about to change with the release with the upcoming HP Prime-review. Despite the lack of new models, the HP 50g has continued to be a popular choice, in fact, the most popular graphing calculator choice among HP fans. Back in the late 90’s when I was an engineering student at the University of Illinois and my graphing calculator of choice was actually, an HP, the HP 48gx.

Click here to buy the TI-84 Plus C on Amazon! UPDATE: (2/10/16) Since I wrote this review a couple of years ago, Texas Instruments has discontinued the TI-84 Plus C. While it continues to be available at some retail outlets like Amazon, I suggest taking a look at the newer model, the TI-84 Plus CE. You can follow this link to my TI-84 Plus CE Review. With so much of the attention from Texas Instruments on the TI-Nspire line over the last 5 years or so, it was exciting news to learn that the TI-84+ family of calculators was getting a much needed face lift with addition of color.

TI-89 Titanium Review

August 29, 2012

Click here to check the TI-89 Titanium Price on Amazon. It’s been almost 2 years since I first reviewed one of my favorite graphing calculators with a computer algebra system, the TI-89 Titanium. The original TI-89, a smaller version of the old TI-92, was released in 1998 after Texas Instruments realized people didn’t want to have to pack a suitcase to bring their calculator to class. The TI-92 was a great calculator, but it was huge and because it had a QWERTY keyboard, it was banned from almost every standardized test (because for some reason the College Board feels that allowing calculator manufacturers to place keys in QWERTY format gives students an insurmountable advantage on the SAT).
