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): TI-30 TI-30 LCD TI-30 II TI-30 III TI-30 SLR TI-30 D TI-30 SCIENTIFIC TI-30 SLR TI-30 SLR+ TI-30 STAT TI-30 Challenger (Solar) TI-30 GALAXY TI-30 GALAXY SLR TI-30 SOLAR TI-30 S TI-30X TI-30X Pro TI-30Xa TI-30Xa/SE TI-30X Solar TI-30Xa Solar TI-30XB TI-30XS TI-30XII TI-30XIIB (this one) TI-30XIIS TI-30 ECO RS TI-30 SR 50 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. F◄►D function (and other fraction keys) can be used to turn decimals into fractions and vice versa. For instance, type the number ".125" followed by using the F◄►D function 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 the x⁻¹ key.
