It can be a chore to teach a class how to use a graphing calculator when you first introduce them to the classroom. You never know how many students actually purchased their own calculator, or the level of understanding of the calculators of the students that are introduced to the class. Finding a useful and durable graphing calculator can be a challenge because of this, which is why I created this list of the 10 best graphing calculators of 2016.

Frequently Asked Questions (FAQ)

Which TI graphing calculator is the best?

Most commonly used; perfect for students in middle school and above.

What is the most powerful calculator?

The TI-89 Titanium by Texas Instruments is the most powerful graphing calculator. It is significantly more powerful than the TI-84 Plus because of its additional functionality, memory, and online features.

The TI-89 Titanium is widely used by high school, college, and university students for its capability of substituting the standard mathematics curriculum with the calculator's computer algebra system. This approximation is not possible with the TI-84 Plus.

You may be wondering why most colleges and universities require students to use a scientific calculator like the TI-89 when the standard mathematics curriculum provides sufficient calculation methods for solving most problems. I doubt that many calculus students are expecting to have to use calculus to answer simple questions.

Is there an online TI 84 calculator?

Yes, there is, but it's not officially supported by Texas Instruments (the makers of the TI 84 calculator). It's an unofficial calculator, and it may have some bugs. The website is here:

Why are graphing calculators so expensive?

; How do I know what calculator to buy?; What models meet my needs?

First off, I want to say that if I have the option of doing homework on a computer, then I won't opt for the calculator. On the other hand, if I'm doing a small assignment that involves mainly simple arithmetic, I'll usually prefer the calculator to a laptop.

While most people would think of a 'calculator' to be a boring, outdated technology, graphing calculators are still the most powerful and useful math tools around. Even though it's possible to submit your math exams from a phone now, there is no replacement for the power of a good graphing calculator.

Conclusion

In a lot of reviews users were clearly interested in an engineering calculator, but found themselves overwhelmed by the number of choices and unable to make a decision. Our team has worked hard to narrow the field down to our top ten recommendations, and we think that if you make a decision based on the results of our tests you will not be disappointed with you choice.
