So far it seems to be a good book to learn how to use the T-84 calculator. For myself I'm too old to try to use it. I bought it for my son to start 7th grade but I was informed that it's to advanced for him right now. The schools to fly list was vague on what they needed. They said they needed a TI 34 or better, but after we had meet the teacher night they said he couldn't use it during testing but he could use the t34. The reason I brought they top it a line calculator. Was not just for this year but through the rest of his schooling. So I wouldn't have to buy a new calculator every year. By the time you buy the calculator the case in the other accessories you have over $200 invested. I tried to do the right thing for my son based on the information that I was given. I'm going to keep it so he can practice using it on his own so when it comes time to need it, hopefully he will have it mastered. He's a average kid so hopefully he figures it out 😊. I looked at it like an investment in his future! Read more

You know the thing I dislike most about any calculator? Is the sound of the plastic back hitting the case when I am using the calculator. The TI Plus CE doesn’t have that problem, thanks to rubber grip studs on both the case and the calculator it is a soundless experience, minus the buttons of course. It’s also nice that the wonderful clip mechanism that will ensure that your calculator will not slide out, if you mistakingly grab it upside down. Mind functions exceedingly well. Despite how Much it can do it size is very portable, easy to slip in your pocket when it’s need is no more. And slip out when a challenging task deems the use of a calculator. Mathprint function is a nice touch allowing you to use functions exactly how you would on paper. For those who aren’t sure what mathprint is, it’s feature that makes equations exactly how you would write it. For example in a non Mathprint equation a fraction would be (a/b) with Mathprint it would be (an over b separated by a horizontal line). My old calculator would delete all of the calculator’s history if I simply turn it off and then turn it back on. The TI Plus CE doesn’t, it’s all there ready to be used again. And of course you can clean it when you don’t need it anymore, just not every time you turn it off. It is a powerful tool ready for. As a student, I height recommend it to other students, most urgently to those about to enter collage or sophisticated high school math/science classes. Read more

the quality of it was good, other than a few scratches. The Display was good and bright. The functionality was also good. The size was good it fits in my backpack. The value for money, I would say it’s a bit too pricey, but given what it can do it kinda worth the money. Read more
