With the Galaxy 40x Texas Instruments introduced an enhanced scientific calculator performing fractional arithmetic. You may use two different modes:
• Euklid's division: 56 / 5 = 11 (Q) 1 (R)
With the SIMP and F-D-key you can shorten results and convert between fractional and decimal display:
With the Galaxy 40sx Texas Instruments sold a similar calculator using solar cells. A more traditional housing was used with the similar TI-32 Explorer Plus and its European sibling TI-40 Solar.
A less sophisticated calculator using the fractional arithmetic was introduced with the Galaxy 9x. Both use identical printed circuit boards inside.
In Belgium, France and Italy a slightly modified version of the Galaxy 40x supported "French fractions", don't miss the Galaxy 40. Think about a programmable calculator in the same package and read more about the Galaxy 67!
The Galaxy 40x found soon its way to the vision impaired people. German based company EHG Handy Tech Elektronik GmbH developed with the Galixa Speech and Galixa Braille two products with natural voice speech output and even a 10-cell braille display.
