Texas Instruments TI-73 Graphing Calculator
Amazon.com Review
The TI-73 is a great compromise for those in the market for a full-featured scientific calculator who don't want to spend a lot of money. The only real problem is that the superior TI-83+ is now available for about the same price, but if you have your mind set on this model, it certainly won't disappoint. The highlight of the TI-73 is its large display, which shows the history of your calculations, depicts graphs and charts, and has a high enough resolution to simultaneously display several rows of stacked fractions. The stacked-fraction feature is a boon for struggling middle school students, as the results of calculations involving fractions are displayed as fractions, not decimals. The TI-73 is fully programmable and comes with a fairly large library of built-in formulas, making things like time and distance conversions a snap. The product comes with two features that few other calculators boast--firmware with flash memory and link capabilities. The use of flash memory means Texas Instruments can upgrade and enhance the features of the calculator and make them available to TI-73 users without requiring a hardware upgrade. Instead, you simply download the new firmware or software applications, connect the calculator to your computer, and copy the new stuff over the old stuff. The package comes with a cable for linking two calculators, but unfortunately, the cable for connecting the TI-73 to your computer is sold separately. Texas Instruments didn't skimp on the documentation and bundles a 350+ indexed manual with the calculator. This tome is chock-full of illustrated examples that demystify the device's more advanced features like statistical analysis, lists, tables, and function graphing. We were graphing within 10 minutes of unpacking the TI-73, and cobbling together simple programs within an hour. The TI-73 is marketed as a calculator for middle school students, but it has enough power and features to satisfy all but the most advanced high school and college students. --T. Byrl Baker Pros:
- Large display
- Comes with a good assortment of built-in functions
- Programmable
- Documentation is excellent
Cons:
- Superior TI-83+ costs about the same amount of money

 Get the 83 or 89 - perspectives from someone who has used a TI for the past 10 years December 27, 2009

This calculator is fine, and TI is certainly the industry standard in graphing calculators...so not much competition there. But I would definitely just pay the extra money for the TI-83 (I had a Plus...but being 22 years old, I am a dinosaur, so can't comment on the Silver edition and what not). Assuming the student doesn't break it, this is the standard through high school and college, so why buy an $80 calculator now, only to purchase another one for $100 in 2 years? It's best to get used to your calculator so you can be efficient on exams, etc...and at some point in high school, the 83 will definitely be much more useful than the 73, if not required.
I had an 83 from 6th grade until my first year of college, when I dropped and broke it. Upgraded to an 89...it helped me out a few times on projects when I didn't feel like calculating out long integrals or derivatives by hand, but didn't help me out on any tests or anything, if that's what you're looking for (most college exams are taken sans calculator - I majored in math).
If your student is at middle school age, I would advise getting the 83 for: 1) increased functionality over the 73, 2) less complicated interface than the 89, 3) most universally used, 4) interesting (but not overly complicated) programming interface, if the student might be into that. I used to program small applications on my 83 in middle school, but when I bought the 89 in college I never took the time to relearn the interface.
Probably best to buy a TI-83 now, and if desired upgrade to the 89 when you hit college, or just stick with the 83 (like most of your fellow students will)

TI-73 Graphing Calculator is bought to my daughter in 7th grade. It is the model recommended by her Math teacher (Middle School).
Depends on what you need a calculator for April 23, 2003

If you are in grades 4-8 this is a wonderful calculator to explore and formalize your understanding of the math concepts. It has many nice features. However if you need a graphing calculator that you will use through high school use the TI-83 Plus Silver Edition. If you are purchasing during your high school years you may want to consider even starting with a higher caliber calculator than this as a TI-83 Plus will not take you through very many college level math courses until you need something more substantial in available functions.
 Good calculator--but I would save the money for a better one September 18, 2000

Well....this calculator has many features for middle school students, but really is it worth it ? If you're in middle school, then you probably won't need such an expensive calculator, because you really don't need to use a calculator to graph. If you are learning graphing, you might not be able to use it one the test. In my opinion, I would buy one of those cheaper plainly scientific calculators. They get the job done and they are cheaper. But, if you really want to get a graphing calculator, I would suggest the TI-83 plus. Right here on Amazon.com, it being sold at $86.99, CHEAPER than this one and with more functions!!!!!!

The TI 73 is the best. At least in my opinion, it is the best for all the people in Middle School. If you are in Middle school at this moment and you need a graphing calculator for math or science, don't go out and spend alot of money on another kind of calculator. The TI 73 is fit for the job!
