Reviews around value (5.00 of 5)
-
This calculator is a great value when considering all it does.
-
It completes all the necessary function and is a great value for the price.
-
The best value for a non-programmable calculator around.
-
Why the calculator doesn't know that squaring a negative number should result in a positive value is something that left me dumbfounded
-
This is our 2nd scientific calculator and it's a great value.

Reviews around buy (5.00 of 5)
-
Hands down one of the best buys for a middle school kid.
-
Overall solid buy and it has lasted me well over 5 years without any issues.
-
The school recommended we buy this specific calculator so it would be wise to check with your school and its math teacher to make sure that this would be an appropriate buy.
-
This one is fairly intuitive, a few things I had to search for solutions for, but all and all a good buy!

Reviews around item (4.26 of 5)
-
I understand the item was inexpensive, but it should clearly state the one you receive is used.
-
ITEM DOES NOT WORK
-
For TI being at the top of the calculator industry for so long, it is apparent that they are slipping and hoping their flaws will have their customers spend more money on their more expensive items.

Reviews around display (3.57 of 5)
-
My only dislike about this (and it is a very minor dislike) is the display
-
Nice two line display that shows the calculation you're doing
-
Don't buy this!!!the display are so bad that you can't see it from the 45-degree angle (normal view when you place calculator on the desk and trying to use
-
It works but I don't like the display, it isn't very bright.
-
Also, I noticed one reviewer mentioned that the display is hard to see and they were right - you have to tilt the calculator a certain degree in order to read it.

Reviews around parenthesis (2.54 of 5)
-
Negatives before the number, you can use parentheses the same way you would on paper, you can enter large fraction expressions using parentheses, and it's all displayed before you hit enter.
-
Bought it a couple months ago, still working as if its brand new down to every single button
-
You may think this gripe is trivial, but when dealing with trigonometric formulas and such, it makes for errors in calculations when running long equations and you forget the burdensome parenthesis
-
Cons: I realize this is the basic layout for many different scientific calculators, but it's kind of annoying that the percent key is a secondary function, meaning you have to press the "2nd" button, and then the left parentheses key to enter a percent
-
Herein thereafter, the division function doesn't work, the parentheses don't work, and the calculator is practically impossible to use

Reviews around exam (2.54 of 5)
-
so you're not doing hard arithmetic for half the exam's time limit
-
If you are fast at entering problems into this you will fail your exams, the device simply can not keep up and will miss button presses.
-
Bought it a couple months ago, still working as if its brand new down to every single button
-
and I'm not going to face a failed exam from a professor
-
No doubt, this problem would be easily solved by the Nspire that I own, but I'd rather spend the extra time and not face a failed exam

Reviews around button (2.29 of 5)
-
The calculator is what I expected it to be, but the buttons are loose
-
My only complaint is that sometimes the buttons can be a little difficult to press quickly
-
While this thing does its job, the buttons frustrate me like no other.
-
My only complaint is that you have to press some buttons hard for them to work
-
the buttons barely worked I'd have to press it hard like three times to take

Reviews around syntax error (2.28 of 5)
-
Calculator works as it should
-
Not as smart as the TI 83 but great for algebra.
-
As others have said, the buttons don't always register on this calculator, so if you aren't paying attention you get the wrong answer or a Syntax Error
-
Bought it a couple months ago, still working as if its brand new down to every single button

its fast, easy to use, accurate, just a perfect machine, especially given my "style" of math problem solving and data recording

Not as smart as the TI 83 but great for algebra.

Reviews around answer (1.90 of 5)
-
You can't imagine the frustration of punching in your calculations again to realize your calculator gave the correct answer, meaning the reason I wrote down the wrong answer on the exam was purely due to a missed punched in number
-
This scientific calculator works well and will give you the right answer as long as you enter it correctly
-
As others have said, the buttons don't always register on this calculator, so if you aren't paying attention you get the wrong answer or a Syntax Error
-
and there's no way I'm going to rely on this calculator because it's very easy to hit a key, think you punched in a number that doesn't register, leading to a wrong answer.
-
Just spoke with TI again, Raphael, due to the calculator becoming overloaded when solving equations; hence producing the wrong answer b/c it is incapable of handling so many numbers.

Reviews around numb (1.85 of 5)
-
Buttons don't react sometimes so I'll type out a calculation and miss a number
-
Bless u
-
More complex operations i.e. conversion imaginary number to polar coordinate work but took a while to get key sequences correct.
-
Sometimes it feels like you pressed the number, but it does not register on the screen.
-
Also not the best for complex number, the Casio fx-115ES plus is perfect for complex numbers (about $17)

Reviews around key (1.83 of 5)
-
The keys are not the easiest to press and they don't always register that I have pressed the key.
-
The keys all still feel really nice, though I can definitely feel some like the equal key are like 5% worn which is incredible for 8 years
-
When I try to type quickly on this calculator, I often find there are missed keys(not wrong keys, but skipped)
-
This calculator is slow and the keys are so hard to press
-
Fist of all the ANS key and the EXP key are soft keys (you have to press 2nd to access them

Bless u

I missed a question on an exam/quiz simply because of this calculator error
-
Because of this I failed many questions that I would otherwise of gotten right
-
Furthermore, I watched a classmate next to me disappointed that she missed a quiz question for this exact reason, and when I asked to see what calculator she had used, it was this exact same model

Reviews around number (1.48 of 5)
-
As you input your calculation, it will often miss numbers or symbols and you'll have to correct
-
At least it doesn't slide all over my desk when I punch in numbers!
-
If you enter numbers quickly it misses numbers randomly
-
The second line is handy in making sure you punched in the right numbers and operators, but is a little cumbersome for longer equations
-
You have to punch in your numbers very slowly and deliberately for it to register

Reviews around bite (1.26 of 5)
-
I found myself slowed down quite a bit during my test when I had to make sure my button presses were being registered
-
This makes me constantly glance at the second line and waste a bit of time in my calculations
-
The cover wobbles a bit on the table when it's on the back.
-
It was described that it's scratched a bit, it come the way it was described

Keyboard could be a bit more tactile but works OK
