What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Our kid's math teacher put up a slide for the parents telling them a lot of school districts mandated the TI, but not our district. He put up a second slide with specs on the Casio for 1/8th the price, then announced if families couldn't afford even that, he had a bunch to loan out for the term.

And in 1990, Texas Instruments basically invented the last one as far as education is concerned

[–] [email protected] 1 points 2 months ago

They still cost about the same now as when I got mine in the late 90s

I felt like such a rebel with my Casio in high school. It was so much faster, had a better screen, and had way more features.

[–] [email protected] 4 points 2 months ago

Yeah before that I heard they were using trumpets to do their math

Does the TI monopoly extend to other states? Guess I never thought about it before, but was almost excited to see Casio's could potentially be used elsewhere

[–] [email protected] 3 points 2 months ago

It extends all the way to europe, TI-84's were a must and still are. They sell that relic for around €100 still.

Delaware checking I'm we basically had the TI 83 or TI-84

[–] [email protected] 12 points 2 months ago (2 children)

A TI83 or 84 was mandatory for us to use back when I was in HS in NJ

[–] [email protected] 1 points 2 months ago

TI-85 for me and most of my classmates. Years under us used 82's, IIRC. My buddy had a ginormous TI-92, though.

Yeah I basically ignored my teacher's suggestions and bought an HP instead because I really liked the Reverse Polish Notation it defaults to. I could do everything the TI could do and in fewer key presses. Took some learning though. Had the side benefit that no one would ever want to borrow it because they couldn't even do 1 + 1 in RPN.
