      Back when we were doing quadratic equations; I wrote a program on my TI-84 that would ask which parts of the equation you already had, and would fill in the rest for you.

      My teacher liked it so much he bought a transfer cable for those calculators so he could get a copy for himself. Then used to to grade tests.

        I did the same thing. It was allowed in general, with the correct thought, “if you can code it yourself, you know the content”

        I had another “program” that would fail to run but that’s because I wrote notes into it. Doubt that was allowed.

          I did that but made it return success before it got to the notes. You had to scroll to get to the notes, but it looked innocuous before that.

          Oh god I remember doing that too. Those “programs” were the best. I even mad sure to make the code long, so that even if someone thought to take a look at the code they would have to scroll for a while to find the notes.

        I could never remember the formula to calculate compound interest.

        But I had no trouble writing a for loop.

            I would just rebuild something in my head like this every time.

            While i < n; k=k+(k*r); i++;

            You’d think I could remember k(1+r)^n but when you posted, it looked as alien as it felt decades ago.

              The use of for makes sense.

              k=0; for (i=0; i<n; i++) k=k+f(i); is the same as k=\sum_{i=0}^{n-1} f(i)

              and

              k=1; for (i=0; i<n; i++) k=k*f(i); is the same as k=\prod_{i=0}^{n-1} f(i)

              In our case, f(i)=1+r and k=1; for (i=0; i<n; i++) k*(1+r); is the same as k=\prod_{i=0}^{n-1} (1+r) = (1+r)^n

              All of that just to say that exponentiation is an iteration of multiplication, the same way that multiplication is an iteration of addition

          What always annoyed me was having to draw charts by hand. Just let me put the data in a computer for god’s sake, the rest of the working is there… I did actually write a python function for one of my assignments which was fine, but they told me not to do it for the exam.

        I made one to decompose polynomials it was very good because it showed all the steps it was literally just copy what’s on the calc to the page

        Yeah but at least work on an enclosed system is always zero. Idk why but I always chuckle about that.

        Sure, you can prove it in like 4 to 8 lines of multivariate calculus, but its always gonna be 0.

      They added wifi with a extra circuit board hidden inside the calculator case. It’s connected to the calculators communication port, and pretends to be another calculator. So they can use the calculator’s built in “send” function to send variables/text/etc to the hidden card, which then uses it’s internet connection to look up answers and send the results back.

      Not sure if it’s the same thing but a few days ago I saw a youtube video where person modded it with a wifi card so it could communicate with your pc which is at home. It required internet access from your phone which needs to be near though.

      It sounds fake because it sounds like they only used software hacks. But they also added a microcontroller board in it with wireless networking

    Its been quite a while since I’ve taken a proctored exam, but then all the proctors would clear all the memory on your calc before they’d let you use it for test. Is that not the case anymore?

      Depends on the exam. Some don’t even allow programmable calcs because they don’t want to deal with possible shit like this. I have already seen a certification exam where they provide the calculators as well.

      The article said it can be download “on demand” so that might make the clearing pointless.

      The launcher program can be downloaded on-demand, avoiding detection if a teacher inspects or clears the calculator’s memory

      If I understood it correctly, the Wi-Fi module appears as a standard calculator-to-calculator interface, so built-in commands can install the cheat apps at any time.

    What would happen if now plug in another calculator? AFAIK that only a P2P connection and never meant for >2 parties.

    Utilizing the tools available to you to solve problems is not cheating, its resourcefulness, and using your brain. Which is of course frowned upon in schools that exist to churn out mindless drones for corporate enslavement.
