Product Description

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

This is a great calculator for a Middle School/High School Student. There are many functions on this calculator that are really useful. Also, there are mini math games, such as probability, etc. Overall, this is a great calculator if you're looking for a useful, long-lasting calculator because this is one of the best calculators around that I have used. Overall, I would recommend this product, as it has a very good quality.

4.0 out of 5 stars The TI 73, August 31, 2000

By A Customer

This review is from: Texas Instruments TI-73 Graphing Calculator (Office Product)

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!

A Kid's Review

This review is from: Texas Instruments TI-73 Graphing Calculator (Office Product)

I use this calculator at school. It is great! It does graphs, plots, and much more! I like how it shows you all of the number that you type in, unlike a regular calculator that only shows you 1 number at a time. It's wonderful for schools and home!
