Disclaimer: Ranking is subjective. May be unhinged towards the end. This is limited to IB exam use, and assumes that your teacher does not do an excellent job teaching graphing calculators. If you have to self-study a calculator, might as well learn a great one at an affordable price. 1. NumWorks. 4.5/5 Finds up to 10 roots at once. Automatically sets the zoom for a plot. Can directly solve for unknown mu and sigma in normal distributions. Lightning fast. Smooth experience. Excellent value with relatively low price. Why pay for fancy apps on other models if they are disabled on the IB exams? 2. Casio fx-CG50. 4/5 Casio's allow you to correct mistakes from many step ago and will re-run the later calculations. It can also find up to 10 roots. Like most of the models (except for NumWorks and Nspire), the coordinates are automatically stored in X and Y. This makes it easy to use them in subsequent calculations, as IB discourages premature rounding of intermediate values. Some downsides include that in rare scenarios, Casio only gives 4 decimal places and rounds down. Does 0.0123 round to 0.0123 or 0.0124 to 3sf? Needs some effort to figure out. It is also missing certain on-screen help, and requires more memorization than other models. 3. HP Prime. 4/5 HP Prime can only find one root at a time, and cannot edit past calculations in place, but its speed and smooth user experience place it ahead of others. Did I mention it's touch-screen? 4-5 (tie). TI-84 Plus CE / Casio fx-9860GIII. 3.5/5 Meet the requirements. The overwrite default in TI-84 is annoying. 9860GIII has more features, but it's black and white, so somewhat balance out. 6. TI Nspire CX II. 3.5/5 Sometimes speed isn't everything. Sure, it's lightning fast. Would be better if key points are stored in X and Y (like literally every model except NumWorks, on which it is super easy to save). Why are settings all over the place? Why do I have to press 4 keys for tan? Why do I need a touch pad? Either make it touch screen or keypad only please. Why the A-Z keyboard? (Side note, IB prohibits QWERTY keyboards on calculators.) What do you mean kx is a variable and not k*x? What do you mean tanx is not defined? What do you mean x(5) is evaluating the function x at 5? Unfortunately the little things annoy me too much. Haven't tried Casio fx-CG100 or the TI-84 Evo. Based on what I have read, CG100 should be between NumWorks and CG50, and Evo roughly equal with HP Prime. As they are relatively new, the resources are less plentiful. For a comparison of ~20 features with key differences, see https://geta7.com/aa-notes/graphic-display-calculators/#feature-chart Hope this helps you find the GDC suitable for you!

(He actually gave it to me on Thursday bc it was the 2nd to last day of school for me, I just forgot to make a post here lol) Basically, all of the graphing calculators at my school were going up for auction or smth because we've switched to just using desmos, however this calculator had some corrosion in the battery holder, so my math teacher was told he could throw it away. However, since he knew that I like collecting and messing around with calculators, and the fact that there's barely any corrosion (as seen in img 2), he just gave me the calculator instead of throwing it away! It took like less than 5 minutes to clean it a bit, and it works perfectly fine. Idk if I'm really going to do much with it, but it's still cool submitted by /u/BurntCheeseSauce to r/calculators [link] [comments]

I already have a TI-84 Python +CE but I was wondering if this is worth getting. submitted by /u/dorkboy75 to r/calculators [link] [comments]

I found a ti 84 plus ce python for a good deal for about $100 new. I need a calculator for AP Calc AB and BC later on, as well as college as I will be majoring in STEM. I'm wondering if the evo is worth the extra $60 for that use case? Also I don't plan on jailbraking it or anything like that, just using normally for my math classes and exams. submitted by /u/StartObjective3669 to r/calculators [link] [comments]
