Technical Details : Texas Instruments TI-73 Graphing Calculator

• Graphing calculator for students in middle grades
• Large display screen
• Easy-to-use keyboard
• Stacked fractions
• Upgradable with flash software to keep up with changing curriculum
• Comes with a good assortment of built-in functions
• Programmable
• Documentation is excellent
  

TI-73 Graphing Calculator 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.

TI-73 Graphing Calculator 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++ read more
