It’s also the very first calculator I’ve ever owned that kept track of the time and date too (and you can see I haven’t set it correctly yet either). Here’s a hint of its sophistication, the screen:

It took me about 10 minutes to figure out how to graph even the most simple of equations, I can only imagine the learning curve for statistics and chemistry calculations. The biggest challenge with this amazing graphing calculator is that it’s so darn complicated. When you can get a four function calculator for a few bucks at the local convenience store and already have a capable scientific calculator on your smartphone, it runs about $115, depending on color.

Fortunately it’s very slim and very light so it’s easy to toss into a backpack or briefcase as needed, and the included plastic cover means it’ll survive the jostling and banging without a scratch or ding.Īnd that’s a good thing, because the TI-84 Plus CE isn’t cheap. It’s also a big calculator, as is immediately obvious when I put my Apple iPhone 6 next to it:Īs you can see, it rather dwarfs the iPhone with its almost 8-inch height. I think the pocket protector is included for free!

It even has an app store through Texas Instruments where you can download apps for specific functionality, particularly in statistics. To be completely fair, the Ti-84 Plus CE is more of a computer than a calculator, just a computer that’s specialized for mathematics, statistics, and the like. Just plug it in via the included Mini-USB cable and it’ll quickly charge enough for weeks of use, either into a wall plug or any other handy USB connector (like a computer or car charger). It also highlights something else worth mentioning: the TI-84 Plus CE is a rechargeable calculator that never needs batteries. That’s because it’s still plotting values – I set the “q” to 99 accidentally, when it only takes about 40 points to define this flower! Look really closely on the top right and you’ll see a tiny yellow circle adjacent to the battery.
Very useful for identifying inflection points, for example.Įmboldened by this, I tried a more complex polar graph using a slightly more abstruse formula: I could also accomplish this with the function, but has the nice bonus of letting you use the arrows to step through values and see the x,y values along the line as you move. So I entered an equation:īy pushing the button along the top it was quickly and efficiently plotted: What it does really, really well is graph equations. This is way more powerful (and complicated) than that. Not quite as confusing as the RPN of HP calculators, but if you’re looking for a basic four-function calculator with some smarts, this is not your ‘droid. To start, I confirmed that you can add 1+1, but with its modern calculator design, the keystroke sequence is. You can see that even the up and down arrow keys have triple duty! It features 46 keys, just about all of which have three functions (standard, blue and green, as the blue and green keys denote), along with a lovely big color screen and even a cursor arrow cluster. You can also see that the calculator itself is, well, somewhat of a beast.
It’s incredibly well ranked on Amazon (4 1/2 stars with almost 200 reviews) and Texas Instruments basically owns the graphing calculator market segment too, muchly with different versions of the TI-84 as technology has continued to improve.Įven better, for high school and college students, the TI-84 Plus CE is approved for use during the Scholastic Aptitude Test (SAT), Advanced Placement (AP) test and related, as highlighted on the package: So reviewing the TI-84 Plus CE was an interesting experience with only a few flashbacks to college math classes.įortunately, the TI-84 is a workhorse of a calculator, one of the most popular calculators on the market. I understand basic math, but once you get to polar graphing, matrices and rotating formula around an axis to compute volume, I’m way out of my league.

First off a disclaimer that I’ve never had to write before: I’m not a mathematician, I don’t play one on TV and I did my best to avoid math classes in college and grad school too.
