Is this four banger really a scientific calculator ? You know basic calculators like the TI-106 sporting the square-root function. And this one ? The MathMate uses the AOS system introduced with the SR-52 more than 20 years ago.

Try this calculation on your four banger: 2 + 3 * 4 = ?
The MathMate gives you the correct answer of 14 like the big brother Math Explorer. Don't miss the stylist and innovative TI-10.

Texas Instruments was always listening for the demands of the classroom. Read some guidelines how to select the right calculator to ensure long-term satisfaction:

	Solar Power: Eliminates the need for batteries. The TI ANYLITE™ technology allows operation even in low light.
	Durability: Plastic keys are tougher and more tamper-proof than rubber keys. An extra window protects the LCD display and the solar cells.
	Keyboard: Color coding helps children quickly identify functional key groupings. Large, well spaced keys are easier to find and press.
	Packaging: With a convenient storage caddy 10 or even 30 calculators are grouped together.
	Functions: Choose a model with only the specific functions you need. Unnecessary functions clutter the keyboard and may impede a student's understanding of the concepts.

In the year 1995 Texas Instruments provided a total of 6 different calculators (not counting the Graphing Calculators TI-80, TI-81, TI-82 and TI-85) to meet the above demands. View a comparision table here.

Stokes Publishing Company, Inc. based in Sunnyvale, California sold a companion for the teacher, view the Elementary.
