Notes: |
The TI-30 series started with the TI-30, an ordinary scientific
LED calculator. But Texas Instruments kept extending this line,
turning it not into just a model number but a whole calculator
series. Trying to make it the non-programmable scientific
calculator for school use.
So far I’ve found mention of the following types (probably incomplete):
The TI-30XIIB and its variant, the TI-30XIIS which has a different colour scheme and a solar cell, introduced in 2005 is still for sale as I write this in 2024. The "F◄►D"-key (and other fraction keys) can be used to turn decimals into fractions and vice versa. For instance, type the number ".125" followed by the "F◄►D"-key and the equivalent fraction "1/8" is shown. This is a scientific calculator with statistical functions and five memory locations "A, B, C, D and E". To enter exponentials an extra keypress is required, "EE" is the "2nd" function of "x^{-1}". |
