Notes: The TI-30X Plus Mathprint is a scientific calculator with a dot matrix display capable of showing mathematically accurate results. It has a nice and clear rectangular look and its keyboard is clear and has good contrast. It is still for sale when I write this in 2026.

Next to the functionality we are already familiar with from its predecessors such as the TI-30XS it has some interesting extras.

First and foremost this calculator introduces a welcome new method to work with keys that usually need a modifier to select such as the inverse trigonometric functions and exponentials. On this calculator simply press sin twice to select sin−1, press again to select sinh and again to get to sinh−1.

The ln log key, the exponential function key e□10□ and they keys for statistical functions and natural constants and i work in the same manner.

Other extra functionality:
  • It has BASE-n capabilities.
  • It can do complex number calculations.
  • It has a library of unit conversions that can be entered as symbols.
  • It has a library of constants that can be entered as symbols.
In my opinion this is a capable and refined member of the TI-30 family. The new method of selecting variants of operators makes the keyboard very clear and unconvoluted.

one drawback however is how difficult it is to replace its two batteries. After removing the screws from the back one has to insert a hopefully non-destructive wedge to lift the front of the calculator off. All the manual has to say about it is:
From the bottom, carefully separate the front from the back. Be careful not to damage any of the internal parts.
Do not use a knife. Use a plectrum like piece of hard plastic.
Series: 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):
