Texas Instruments TI-73 Graphing Calculator Overview

The Explorer TI-73 ViewScreen Graphing Calculator joins our popular line of handheld technology, providing a larger screen alternative for teachers who feel limited by the two-line display of other fraction and scientific models. The Explorer TI-73 is completely compatible with existing TI-73 classroom accessories and related curricular materials for upper elementary through lower middle grades, from fractions through pre-algebra.

Texas Instruments TI-73 Graphing Calculator Specifications

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
