1. A joke vs Casio calculators that even can run python.
https://www.casio-intl.com/in/en/...s/fx-CG50/

2. Emulators for pc
https://education.ti.com/en/softw...ti-84-plus
http://wabbitemu.org/

For those at home during the lockdown....

3. https://www.mathway.com/
But seriously made obsolete once the slew of step by step math solvers arrived online.

Slew of phone calculators, too, for free.

4. Of course, it's the idiot behind the calculator one must worry about, which is why I have NO IDEA why calculators are allowed on standardized tests when everyone was able to solve math just fine with pencil and paper last century.

It is not like trig thru algebra thru calculus has changed suddenly.

Of course, hilariously sad when I'm at the checkout, rings up $6.12, I give $7.00, cashier rings up change at $0.88, then I give $0.25 more to cut down on the change I have in my pocket and THEY CAN'T FIGURE IT OUT IN THEIR HEAD!!!!????

....

Yes, always buy used on eBay $20~40.
Unlike other tools and such that have an advantage new, there's nothing that'll benefit you new except the math of $88-20 = you've been screwed out of $$. It's in such ample supply, no point new.

But honestly - TOSS the calculator!!!
Only use tools like Mathway at home to correct mistakes as you learn, but learn to do everything by hand fast. Most can practice to get fast enough that they'll match and beat calculator users on tests all the time.

Once you're past calculus, you'll either be using industry specific software like cfd simulators for calculators far too time intensive by hand, or Mathematica.

I would not recommend this model at all. Go with the color 84 Plus CE version. It is much easier to visualize equations and a much better machine in general. It's rechargeable as well. It's $99 right now and may be cheaper with a staples coupon. The best TI calculator in my opinion is the Nspire (blows both of these machines out of the water but I know most students may not want to learn it by themselves since the teachers "recommend" the 84). Best graphical calculator overall I've ever encountered is the HP Prime. Has a touchscreen and the user interface is great compared to TI but again no teacher will explain how to use it since they've basically been locked into a TI monopoly with TI basically setting a standard back in the 90s.

Also in the future these are going to disappear. Desmos has released an app that locks your smartphone while taking a test and this has been approved for some state and possibly national testing in the future. Good riddance in my opinion. There should be no need for a dedicated calculator device to exist in this day and age.
Desmos test mode, unless they've changed it since I last recall having a kid use it this past school year, just has a timer to show how long it was in test mode, but doesn't lock the device down. The district had to push out the lockdown version for specific days of district testing only, and it wasn't available for in class tests.

But I agree that we are moving away from the TI empire, and I'm mostly ok with it. I love the Nspires though, but don't require my students purchase them. I had my students download the TI app during at-home learning this spring while it was free so they could still use a familiar calculator format.

The CE version of this calc is better though, especially for graphing with different colored data instead of just mono color.

It seems like these graphing calculators have been artificially high for a long time.
They're required for high school so the price has always been high. I have been buying them near the end of school years and flipping at the start of the school year for the past couple years. Really easy money maker. You can almost always find at least one at a yard sale too lol. Yard sale price is usually 1-2$ or less and I'll find them on fb market place or offer up for 10-15$ and then Flip them using Fb/offer up for 30-50$ depending on condition. It's the easiest sale too because I'm selling for like half the price of what Walmart or target sells them for and they usually won't order them online because they've waited till the last minute and the kid will need them for a test the next day.
