Texas Instruments TI-36X Pro Scientific Calculator

This is the best calculator for calc 2 and econ that is allowed at Purdue, if your guidelines are nongraphing and nonprogrammable, this is the best legal calculator that does definite derivatives and integrals, saving time on exams. I have also used it for taylor series if you do the algebra then get the derivative. It does parts, it does reverse power rule, it does like any definite integral.

I own a Casio -115 ESS Plus. Compared to the Casio calculator, this TI looks very impressive. I really like the Casio, but there are more functions on the TI, your calculations are retained even when the calculator is turned off(not so with the Casio) , and there other features which make the TI a very good choice. I do not like the buttons for division multiplication, minus, and plus on the TI calculator. They are etched on chrome, and a very hard to read. However, I used a sharpie to make it more readable, and it seems to work fine. I have now started using the TI, and have put the Casio aside.

Thanks for having this item in stock via online. We looked several places and found out it was a hot seller! Whole process from ordering to picking up at store of my choice was great!

Easy to use, works good no sticky rubber buttons, I will describe it like a gamer keyboard type of calculator providing reliability per fast use for students. Required for my statistics course, no issues with product and saved me $20 ordering from Walmart.com and next day shipping was excellent.

product is exactly as described and came on time. Thank u!

Great for school it was requested.

l bought this specifically to take the Amatuer Radio test. It did everything I needed to pass the Extra Amatuer license exam.

Easy to use for high school Math.

Grown adult returning to college so spending a ton of money on a calculator was not something I was willing to do. This one worka fine; some of the buttona (turning it on, for example) are in odd spots on the keyboard.

Extremely difficult to figure the moves needed to do fairly simple things such as save and recall. Need to use the shift button for many things and the writing above the keys is not very clear.
