I'm not a student; I'm an adult engineering professional.I really enjoy the CAS system that factors, extends, factors, solves, simplifies, and solves algebraic formulas. There is no requirement to transform equation systems into matrices. Don't stress about algebraic blunder. The fact that expressions may be variables is great since it makes replacement a breeze.I used to use a TI-82, which is still functional. I therefore felt somewhat at ease, but I still needed to watch a few YouTube videos to understand the main points of the papers and a summary of the features. The fun and power gradually become apparent as you read the manuals, watch movies, use Google, etc.I set up the software; the calculator has a license, but you must download it from TI's website. The software works flawlessly to transfer files to and from the calculator, upgrade the firmware to the most recent version, and emulates the calculator so that you can use your computer for editing, screen sharing, etc. Very cool.Although not as tough-feeling as my old TI-82, which is constructed like a tank and has withstood numerous drops and abuse, the build quality appears strong. For this one, I purchased a padded cover, which I don't believe is necessary for the previous models.

Imagine my surprise when I found out that my old TI-83 didn't have enough power to do everything I needed it to do for my next three math classes, College Algebra (math 114), Calculus for Business and Stats! After a lengthy conversation with my Math Professor, she recommended I pick up a TI-84 and if I was willing to pay a bit more get the color version. Man am I glad I did. This Calculator is so much fun. It's like walking around with a mini computer in my pocket. I can put in my functions Ysub1 and Ysub2, Hit graph and whamo out comes this pretty graph, like the TI-83 it does handle a lot of numbers, you can set equations to zero and off you go running, however unlike the older version, you are not constrained with having to remember when to use or close parenthesis. I've run the same things through both calculators and was amazed when the older version basically had a heart attack when the TI-84 chugged through the answer.This one is rechargeable, which means you need to plug it into the wall and top off the battery, it comes partially charged. Color changes are super easy with just a touch of a few buttons. Outside of that it does have a larger memory so upgrades are a breeze. I an unable to speak at this time as to the battery life as I just bought it this week and haven't had to charge it but the one time.Whats in the package:1. TI-84 Plus CE1 - Micro USB/ USB Mini-B port1 - USB/USB Mini-B port for charging1 - Cover1 - TI-84 Plus CE for Dummies pamphlet2 additional pamphlets for the TI-84 Plus CE1 -Warranty pamphletThis is really a good upgraded calculator that meets the needs of those who are going to school for general math and moving on to stats. I'm a business major so my math will end at Stats and Calculus for business. I really do like this new unit!

This calculator is fantastic! It has greatly facilitated my life as a math and science major. Although learning how to use it was rather challenging, once I did, it was like entering a completely new world. I simply asked a professor, and they gave me the fundamentals. The rest I simply worked out through making mistakes. Math can be challenging, particularly with out-of-date calculators. Compared to previous calculators I've used, this one is far more versatile. There are numerous extra features that alone make it worthwhile to pay the money.

Looks quite similar to the TI-85 that I used in algebra/trig twenty years ago. So, I think, don't fix it if it isn't broken! Although it was about 30% more expensive, I got our daughter one of the more expensive new color display versions that their school had approved for usage, but it seemed like no other students had one, and the teacher didn't know how to use it either. Lesson learned: just get the cheapest model that has been approved as that is what everyone else is doing and what the teacher will be able to utilize. That calculator is in this venerable old machine!

The TI-84 calculators are required in all of our kids' schools. I apologize, but this is such a con. Calculators that are too expensive: It is disgraceful that TI and instructors are involved. Instead of being so actively involved in the fraud, teachers should work to promote competition so that TI calculator prices are more reasonable for all students. Yes, textbooks are also to fault (someone could look into a case involving anti-trust), but teachers can still speak out!For a total of three TI-84s for our two children. Two TI-84 calculators have been stolen. At that point, we made the decision to stop wasting money on the TIs. purchased this Casio instead.We shared the same worries as other reviewers that textbooks and instructors only teach the TI. But after two calculators were taken, we decided to take a chance. Some reviewers had criticized the manual's lack of information. The calculator is pretty simple to use, though I'm sure there will come a time when reading the handbook would be helpful. Without consulting the user manual, I was able to graph polynomials, resolve systems of equations, etc. I then demonstrated how to utilize them to my daughter, who is a high school student learning Algebra II. She said that she could always find a YouTube video on how to do what she needed when I asked her how she was doing with the calculator after that.In conclusion, a wonderful calculator that costs less than half as much as the TI, has a lower risk of theft (which may be why teachers only use TI calculators when teaching), and does all of the same functions as the TI with a much friendlier user interface.

This is the standard for graphing calculators for high school and early college-level mathematics; the calculator is a pleasure to use.This device is approved for SAT/ACT/AP exams.I have been using this device for two months for Calculus 1, and it is accurate all the time.The box includes the calculator, slide case, mini-USB cable, I/O cable, getting started guide, CD-ROM, and four AAA batteries.The device is powered by 4 AAA batteries and a lithium battery backup to protect RAM. It has a 15 MHz processor, 480 KB of ROM for data and app storage, an I/O port, and a mini-USB port, which can be used to load apps found on the Texas Instruments official website.Additionally, the calculator comes preloaded with 12 apps. Cabri Jr™ (interactive geometry), Conic Graphing, Inequality Graphing, and Probability Simulation are four of the most useful preloaded apps for most students.The five keys at the top of the calculator (y=, window, zoom, trace, and graph) and their second function keys (stat plot, tblset, format, calc, and table) are conveniently placed for students to graph and view a table of x and y values for the function.The calculator has shortcut keys for common functions such as x^-1, x^2, sqrt(x), 10^x, and e^x. It also has the mathematical constants pi and e on the right hand side of the calculator.SUMMARY:PROS: Good all-around graphing calculator for high school and early college-level math; apps can expand this hardware's feature set; calculator is approved for SAT/ACT/AP exams; long battery life; great user interfaceCONS: This calculator is a bit expensive, considering the cost to produce this hardware; it doesn't have a computer algebra system, so it lacks features such as taking limits, finding partial and total derivatives, finding some indefinite and definite integrals, matrix operations, and advanced statistical computation. If you need a computer algebra system, you should go with the TI-Nspire CX CAS or the TI-89 Titanium Graphing Calculator; both are permitted on the SAT and the AP. If cost is a concern, get the Casio fx-9750GII Graphing Calculator, which has similar functionality to the TI-84.

This calculator is AMAZING. Compared to the calculators I used in middle school, it is entirely different. This calculator is incredibly light and thin. Not to mention, I like how it may now be organized a little bit better with the usage of different colors. Although it is obviously a bit expensive, these items last for YEARS (provided you took well care of it). I recall reading about someone who bought this for middle school and continued to use it in college. It's SO handy that you can simply charge this with a USB cord as opposed to the older models when you had to switch out the batteries. I invested in a protective case for it for organization and protection, and I advise others to do the same if they plan to purchase an expensive calculator like this.

I bought a refurbished TI-83 from a third-party seller, and it works great for my college classes. I did not want to buy a new one since Texas Instruments charges too much for an old technology calculator. They have a large monopoly for students who go to grade schools and colleges. Since many schools require their students to buy them, they are making a killing in profits while the calculator costs only $20 or so to make. Most cell phones can do the same thing at faster speeds, but most schools don't let students use them on exams to prevent cheating. I wonder why the Federal Trade Commission doesn't stop TI's monopoly on their calculators? I do like my unit, but I wish they weren't so expensive since this technology has been used since 80s.
