Share a story, ask a question, or start a conversation about (almost) anything you desire. Maybe you'll make some friends in the process.


RULES

  1. Be respectful: no harassment, hate speech, bigotry, and/or trolling.
  2. Encourage conversation in your OP. This means including heavily implicative subject matter when you can and also engaging in your thread when possible.
  3. Avoid controversial topics (e.g. politics or societal debates).
  4. Stay calm: Don’t post angry or to vent or complain. We are a place where everyone can forget about their everyday or not so everyday worries for a moment. Venting, complaining, or posting from a place of anger or resentment doesn't fit the atmosphere we try to foster at all. Feel free to post those on !goodoffmychest@lemmy.world
  5. Keep it clean and SFW
  6. No solicitation such as ads, promotional content, spam, surveys etc.

My favorite was 9, you decrement the unit position and increment the 10s position

Open your hands and turn down the Nth finger. 9•N is the the number of fingers to the left of it in the 10s position and the number of fingers to the right in the unit position.

What sorcery is this!

[–] boonhet@lemm.ee 3 points 3 weeks ago

9 is fun. Start counting up and down from 6 and 5 respectively. Multiply by 9. You get two numbers from the same two digits. 54,45. 63,36...

wait is that not how everyone does it 😂

[–] starlinguk@lemmy.world 4 points 3 weeks ago (2 children)

That's literally the easiest table.

[–] Hossenfeffer@feddit.uk 6 points 3 weeks ago (2 children)

The 0 times table would like a word.

[–] NorthWestWind@lemmy.world 5 points 3 weeks ago

A word and one word only

Which schools teach the 1 and 0 tables? Mine certainly didn't. We learned 2 to 12. IMHO the most difficult one is 7.

[–] Hossenfeffer@feddit.uk 2 points 3 weeks ago

Any decent teacher will do 1 and 0 at the very beginning. It takes, like, 10 minutes and puts the tables into context.

Oh, at first I thought that was crazy, but I actually do the same thing.

[–] kokope11i@lemmy.world 3 points 3 weeks ago

Whatever works for you. I take half of the non five number and stick a zero on it. Plus five for odds.

[–] dicksteele@lemm.ee 3 points 3 weeks ago

I use 5, 8, 11, 17 and 35 times table daily. I would say it’s best to practice repetition if you want to remember something. Plus your teachers lied to you, you will always have a calculator with you!

It has never even occurred to me to do it this way. May actually start, myself.
