The Math Explorer is another calculator introduced by Texas Instruments to perform fractional arithmetic for elementary school. In opposite to the Galaxy 10 the display size doesn't allow scientific notation. Nevertheless calculating accuracy is 12 digits !
Production of the calculator was started in Taiwan. Later products were assembled either in Italy, Malaysia and China with minor design variations.

Later the same keyboard layout was used with a more stylish housing. Compare it here.
A very basic calculator for pupils was introduced with the MathMate.
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
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
• 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 comparison table here.
Stokes Publishing Company, Inc. based in Sunnyvale, California sold a companion for the teacher, view the Intermediate.
The TI-12 Math Explorer was mentioned in TI's press release dated August 15, 2002 to celebrate the 35th anniversary of its invention of the electronic calculator.
