Start Your Back-to-School Shopping With This $10 Texas Instruments Calculator


Based on my background as an engineer, I can talk about the usefulness (think: necessity) of having a good calculator. Throughout my college and graduate school, and even in my engineering work, Texas Instruments is the only brand of calculator I use. It really is the gold standard of calculators. Alright, I’m starting to sound a bit cheesy here, so I digress.


At this price, this calculator is a great option for a high-quality scientific calculator if you don’t need it for graphing. With its two-line display screen, you can see the input you’re typing as well as the output. This makes it easy to see if you entered something incorrectly and quickly make changes.

Besides the graphing capabilities of a more expensive calculator, the TI-30XIIS can perform most of the same functions. It handles multivariate statistical problems, works in three different angle modes, and can even be used in different Falsetation engineering modes.


This calculator comes with a battery included, so all you have to do is put it in the back of the calculator when it arrives and you’re good to go. It also has a small solar panel built in above the screen to ensure that it will continue to work even if the battery goes bad, as long as it gets some sunlight!

Just in time for school to start again, visit Amazon today and pick up a new Texas Instrument TI-30XIIS Scientific Calculator for $9.99.
