Me searching the place for my old Ti83 after stumbling on this thread.
My partner: why are you even looking for this thing??
Me: Somebody on the Internet is WRONG.
My partner: Good enough, I'll help!
I know, it's good to have someone in your life with priorities.
I happened to have my ti-83 plus next to me. I got 16!
YES finally, some sense in here. 🤣
I ended up downloading a Ti-83 emulator because mine has been devoured by the magical house gremlins.
Except TI calculators also give the wrong answer when a bracketed term has a coefficient.
Then I admit I'm wrong, I just don't get how PEMDAS/I got it wrong.
Short story, PEMDAS kinda sucks, because it has 4 levels of priority, but 6 letters:
M and D are the same level, priority is from left to right.
A and S are the same level, priority is from left to right.
Just tested this on a Ti-83 too.
8/2(2+2) = 16
My one big criticism of the Ti-83/84 is implicit multiplication. Ti says 1/2x is 0.5x when I needed the reciprocal of 2x.
Yeah, that's exactly the problem with TI calculators - ignoring the rules of Maths.
My calculator gets 1. Weird.
That is the correct answer.
I thank you for proving me right, but this a 4 month old thread. Not complaining, just giving you a heads up.
Yeah, I know, but it'll show up in search results for all eternity, and it's full of disinformation. As a Maths teacher/tutor who is sick of hearing "But Google/Wolfram/TI says...", I'm doing my best to try and get said people to fix their damn calculators (and also make people aware that those calculators are wrong. (sigh) I miss the old days when all calculators gave the right answer - what happened??). If you feel the same way then feel free to share my links - that's what they're there for. :-)
And right at the moment I'm feeling too tired to do anything which requires me to think about it, so just doing what I can do on automatic. ;-)
And also if I hadn't been replying to this thread then you wouldn't have got the proof that you were right. :-)
I love you brought the TI truth lul
TI calculators disobey The Distributive Law and give the wrong answer when a bracketed term has a coefficient.
You got it right
