Calculate84 Hack 1.7.9 + Redeem Codes

This calculator is a great way to avoid spending $120-$200 on a Ti84 calculator. However I have found some bugs when it come to running some of the statistic test such as 2propztests etc. however for the majority of your functions, you can’t get a better calculator. -response to developer: The errors I found were in the statistics tests under “STAT —> TESTS”: 3,4,6,9,0,B,and E. Basically any distribution with 2 samples or lists would not provide z score, p value, etc or necessary test statistic/parameters. (It would merely summarize the data I entered and not provide the solution.) -2nd response: Here’s one but I won’t do one for all the tests I listed as they run on similar principals. 2-sampleZtest Standard deviation 1: 4 Standard deviation 2: 5.1 X bar 1: 13.6 N1: 200 X bar 2: 11.6 N2: 11.6 Null hypothesis: not equal to mu ——- Expected answer: Z=4.36… P=1.28…* 10^-5 X bar 1 : 13.6 X bar 2: 11.6 N1: 200 N2: 200 ——— Received answer: It used to summarize the entered data but now appears the same p and z values are now presented. Thanks for resolving the issue.

I’m a 3rd year mechanical engineering undergrad, and holy lord crap this is the greatest thing since Betty White.

1. It feels good
I’ve dealt with many apps that have claimed to be this, or have tried to be this, but this is the first that actually feels like I’m using a graphing calculator. As someone who swears by TI-84, it’s incredibly intuitive and has lots of added features to make it more user friendly. They did a really good job of incorporating the power of smartphone to augment the traditional TI-84 experience.

2. Responsive developers
When I first got this app it was still a work in progress, and I sent in feedback asking for them to add matrix functions. Not long after, the UI for handling matrices is by far the best from any calculator I’ve ever used.

3. Portability
It is still a phone app, so it’s not a perfect remedy for having a physical graphing calculator in every situation, like tests. That being said, nothing beats leaving your clunky calculator at home as you go to classes. I use this app so much more than I do my actual TI-84, which I regret spending over $100 on!

so overall this is a pretty good graphing calculator emulator for your phone. I like how it vibrates when you hit buttons on it to let you know that you actually hit the button. so far the answers it gives all seem to be correct also. unfortunately, it is missing a lot of important things. It can do linear regressions, but no other types of regressions. I assume the developer is working on adding those but they should really be near the top of the list. they are part of basic pre-calc so they should be added asap. I will say that as of right now it is definitely the best one available for free because the other ones lock literally everything behind paywalls but still let you download it for free which just seems like a scummy way of boosting downloads. if you add in regressions, i’ll bring my rating up, but it wont be 5 stars until all commands are available.

I am amazed, continuously, at what developers can do these days. I forgot my TI-84 at home when I had every intention of grinding through some stats homework at school (I’m in college and taking a few online classes).
Obviously, it is no substitute on the exams, but when I figured out I could do combinations and permutations and summations, I was so happy!!!
No more switching calculators between backpacks, I’ve found my solution. Keep working on the apps function and the developers will make money off of this. There is even a copy function if you click the equation (highlights pink) and you click enter, just like normal. I look forward to testing the limits of this calculator and seeing what changes can be made. Good luck!

If you’re an online student there’s honestly nothing better than this app. Not only does it perfectly match store bought calculators, it actually makes using it simpler. For example, when finding the peak of a curve, with a normal calculator you have to find 2 points close to the peak, then click to find the max/min. With this app, it automatically tells you max and min of peaks and valleys in graphs. When problems have multiple steps, it’s the small stuff that makes your life ever so slightly easier that you tend to remember. If you don’t need a physical calculator your best bet is down loading this app.

I am an engineering student, and I am always in need of a calculator handy. There’s quite a few great apps out there that can be used as a graphing calculator, but getting used to different user interfaces is always a pain when switching between calculators. I’m used to the TI-84 Plus CE, and this calculator is exactly identical to a TI-84 Plus. Not all the functions of the calculator are available yet (the apps button currently does not do anything) but most of the functions that are necessary to my work are available (like matrices and trig particularly). Overall, this is a great app and I never usually leave reviews, but had to give my opinion for amazing app.

There’s functions such as the NormalCDF and NormalPDF functions. On my physical calculator, there is a menu that pops up to input numbers like it does with the PropZInterval function. It lists the Values, you put the numbers in, and then press calculate. It’s just slightly tedious having to enter in the numbers inside the parenthesis, because you have to remember where the numbers go. Some calculators have this option, some don’t. if this calculator could have that, I would be set for life on this app. Really an epic app. Thanks.

Super smooth and works almost exactly like a Ti-84 from my very limited testing. The Ui is well designed and there are no ever present intrusive ads. It was actually recommended by one of my teachers when I was in algebra 2 as a possible replacement for a calculator. Still, of course you can’t use something like this on a test, and as far as I can tell it only has linear regressions, which makes its use cases limited as years go by. Still, it is definitely worth downloading for younger students who don’t want to spend the equivalent of 60 popeye’s chicken legs for a calculator.

Ive been using this through my math classes for years to avoid spending $100+ on a calculator and its so amazing. recently they updated the app and wrote an honest message about how they were finally going broke, but they knew people couldnt always afford it and they wanted to keep things accessible, so they clarified they would be adding ads, and honestly thats all I ask of apps. Honesty and respect. I love that they just talked to their users like human beings and still care and arent making people pay for it. I will watch a million ads for you guys. thank you

I know how to use a ti-84, they’re expensive and I can’t take one home but I’ve got one on my computer that does the same thing. I needed to punch in a bunch of derivatives of inverse functions which is a pain to do on the computer. I resorted to using Photomath to try and get it to solve but that doesn’t work so on a whim I downloaded this app and omg.
It does exactly that you’d expect, all the shortcuts are the same, it’s got the capability to do all the calculus I need, whoever reads this from development go pat the creators on the back because I am so thankful
