Customer Ratings & Reviews

My old Texas Instrument calculator lasted until my 4 years cousin throw it in a bucket full of water. When we found it won,t turn on. Lasted for more than 5 years without a battery change. Great display and small size makes it easy to carry around. Went to the store to buy a replacement. Love Texas instrument brand.

The TI-30XIIS is a robust, entry-level scientific calculator from Texas Instruments that combines affordability with a range of features, including a two-line display, dual power sources (battery and solar), and broad exam acceptance. The "TI" stands for Texas Instruments, "30X" denotes the model number, "II" signifies the two-line display, and "S" represents both solar and battery power options. Texas Instruments has done an excellent job ensuring that this calculator, despite being entry-level, does not skimp on quality or features. Pros: Affordability: I purchased this calculator for my middle school child. Although it was on sale at a different retailer, I was able to get a price match at Best Buy. Two-Line Display: The TI-30X IIS stands out with its two-line display, which allows you to view previous computations without having to redo them. This feature is especially useful for complex calculations, as it lets you scroll through expressions without losing track. Wide Range of Features: Suitable for general math, pre-algebra, algebra 1 and 2, statistics, general science, and geometry, this calculator offers functions like fractions, conversions, basic scientific and trigonometric functions, 1 and 2-variable statistics, and editing options like cut and paste. Power Options: The calculator can be powered by either solar energy or batteries, making it virtually maintenance-free with its solar panel. Exam Acceptance: The TI-30XIIS is approved for use on SAT, ACT, and AP exams. Cons: Nothing significant. Final Verdict: This calculator is an excellent choice for an entry-level model. While it may not have the advanced capabilities of higher-end calculators, it performs its intended functions well. With its dual power sources, it’s likely to remain functional for many years. I am very satisfied with this purchase and understand why it is recommended by middle school teachers.

I love this calculator, it is the second one that i have bought... only because first one was lost. I would be lost without it. I had a different kind years ago but did not like it. I heard good things about the Texas Instrument Scientific Calculator and all my math teachers said this one is the best to use, that is why I bought it not just once but twice.

I had to buy this cuz I returned to school. Just like back in high school remembered how to use after a few minutes.

I love this calculator! Very easy, simple, and straight to the point. If you take college algebra, need to compute finances, etc, I encourage you to invest in this!

Works great for my Stats class and at a reasonable price.

Good and easy to use scientific calculator for school or home.

Had an older version of this in high school and used this more than my graphing calculator. Used this to double-check answers. A great calculator for a middle schooler taking high school math courses. It can do all the necessary calculations needed for up to PreCalc. This is a great value for the functions included without having to buy a graphing calculator.

This calculator is a lifesaver! It’s easy to navigate, and the buttons are sturdy. It works perfectly for algebra, geometry, and physics. Affordable and worth every penny

I needed a replacement for my 40+ year old scientific calculator. The TI-30X IIS has a nice touch and not too small. Using solar power with a battery backup is a good design. It switches easily between scientific and engineering, and floating to fractional notations. Basic trig and most popular functions are activated in one step. The internal value of pi provides decent accuracy. One option not included in this Calculator is the ability to store and use personal equations. For the price I would class this calculator as a good value.

Got this caculator last minute for my act test. Not every caculator is permitted for the test, so I was a bit scared they wouldn’t allow it, but it turned out pretty well. For all the high schoolers out there about to take the sat, act, or whatever this is the perfect caculator to do so.

I love this calculator! the functions are easy to use, it is solar powered and the device is easy to hold.... if you need a scientific one this is the one to gete.

This is the second of these I've owned, the previous one kicked the bucket after 10+ years of use. Good calculator, buttons are a bit finicky at times but for the price, its not bad.

Good calculator for the price. It is solar powered and the display is very easy to see. The calculator has lots of functions that can solve most types calculation.

Works very well for freshman algebra. My son was getting a c- with a Casio calculator. I bought him this Texas Instruments calculator and well he’s still getting a c- but he seems a lot happier with the calculator. I hope they teach him what all the buttons do by the end of the semester. If you buy this calculator you are making a very budget conscious decision.

One of my kids uses this for school. The two rows is a great feature. This calculator was easy to learn, it's been reliable, and it doesn't use batteries. This is great when you don't need (or can't use) a graphing calculator. Works well for most math classes.

Love that Best Buy price matched. Great value, easy to use, and solar powered.

Easy to use and read numbers. Light weight and convenient to store in backpack

It is good for my son to use in high school. He’s in the 9th grade.

I am really glad this model is still available. It is the most user-friendly in this category on the market. My original one (including my entire home) was destroyed in the Eaton Fire in January, 2025!
