The Best Calculators for School! | Do You Really Need an Engineering Calculator?

Hello, my name is Justin. I am a certified math teacher and have been teaching math for 8 years. I have an undergraduate degree in mathematics and a graduate degree in business administration. I have taught a myriad of subjects ranging from: Pre-algebra, algebra I, geometry, algebra II, and college algebra + trigonometry. If you have any question and/or comments please leave them in the comment section. Be sure to subscribe as I hope to be able to bring short math lessons every day to you and your family.
Mr. J

I’m still using the Ti-89 I used in college. Have in on my desk right now. 

Office Break Gaming says:

My god. I purchased a TI-89 back in 2000. I was a sophomore in highschool. I still use it today. I can’t believe that they still make it today. I’m freaking 32 now…

Pinksugarelephant says:

So if I’m going to do basic statistics and financial calculations, should I just get a TI 30XS? Thanks!

ateb3 says:

does the ti 89 do complex math too?

Brendan Hobbart says:

So you base your advice on how much free stuff you can get from a company. Some teacher. Wow.

flashy3063 says:

In my opinion, the Casio fx-991 ES Plus is better, but it’s more expensive. It can differentiate and integrate as well. There’s also a complex numbers functions too.

The Jeffrey 27 says:

So you stopped recommending a calculator brand because they didn’t give you free stuff for advertising their calculator?

Brian Tumor says:

Why are you trying to talk like a poorly educated black person with attitude problems? Fuck yall, biatch.

Impedancenetwork says:

I hated that damn TI-89 calculator. If you are an engineer you use an HP. RPN rules.

Richard Zheng says:

I do not recommend Casio fx-300ms because it doesn’t have a fraction key and it doesn’t suppose complex numbers. If you are going to buy a scientific calculator it needs to have complex numbers in it. I recommended the TI-36x pro if CAS is banned because it has the scientific constants, matrices, solve simultaous equations and conversion tables. but if CAS is allowed get the TI nspire cx CAS because it can store 100mb of notes, has a spreadsheet function and it has colour for graphing multiple functions

Falcrist says:

You’re recommending the Casio fx-300 over the TI36?

The TI-36 is the direct equivalent to the Casio fx-115, which is way more powerful than the fx-300. Those two do definite integrals, differentiation, matrix arithmetic, crazy statistical stuff, and are freaking amazing at complex arithmetic (both of them have the ability to take polar notation as input). Not to mention the freaking textbook-style input, which is absurdly better than regular algebraic.

Also, no mention of HP calculators? Bro, what are you even doing? The HP50 wants a word.

Luz Fraterno says:

Very informative! Are there any calculators that combine the scientific-graphing features with business (present value, future value, NPV, IRR, etc)?

梵天丸 says:

No calculator, you need to calculate NOW! Just kidding. My 200 and 400 level professor has no issue with any calculator, but my 300 thermodynamic only allows no better than a Ti30x pro.

Neelkanth 123 says:

the Casio fx 300 es plus is also really good for school and the TI 30X 2S is great for basic high school and sometimes even post secondary depending on what u pick to do

Craig Diamond says:

The best calc is the Casio FX-115ES PLUS / FX-991ES PLUS C

GhettoMist says:

The Casio is the best scientific calculator I’ve used.

Greg Nixon says:

TI 36X Pro. Best all around calculator for the money and for your needs in high school. About $20. Not a graphing calculator, but is a scientific one. Easy to use and has a short learning curve. Does an amazing variety of work. Solar powered. Exhaustive library of how-to videos on YouTube for it. I’ve had one for years. Don’t buy a graphing calculator till you absolutely need one. You will find that you need one less than you thought that you might. See what your school can provide for you before you spend $100+ on a calculator.

Arthur Mendoza says:

Is this good for a surveyor?

Philthy Phil says:

What about the TI-Nspire CAS? And by the way, you CAN use CAS calculators on the SAT. I am looking at their website’s list of accepted calculators now. The TI-89 is on the list, as well as a bunch of other CAS graphing calculators. I don’t think that you can use them on the ACT

Heisen Sanchez says:

the solve function of the casio 991 ex is super fast and it doesn’t lag when you’re typing a really long function
