Texas Instruments TI-36X Pro Scientific Calculator

Quality calculator with endless possibilities. For the inexpensive cost, this is such a great buy. I highly recommend this calculator and the Texas Instruments brand. IMHO, they make the best calculators on planet earth, such a fantastic company. * With its case on, the calculator is the following dimensions: 7.2 inches long, 3.3 inches wide, .6 (6/10) inches thick. * The included battery used for this calculator is the following: ONE of these = CR2032 (3.0 V, 220 mAh).

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.

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.

This is the only calculator for doing algebraic functions and simple math for taking Ham Radio certification exams. Another plus is the always charged status since it has excellent solar cells.

I love it, the catulator is work and I didn't know it had a a lid to cover. I recommend it this :>

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!

My son uses it everyday. Works great.

Terrific option for most middle school needs.

Great calculator at a great price

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.
