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 !

The
internal construction of the TI-12 Math Explorer makes use of a clean layout
with a Toshiba T6M39S single-chip calculator circuit.

The calculator was produced in different countries, find an
