  1. Teaching the kids to count in French. I seriously don't see why anyone would find it difficult...

  2. Alright, future engineers!
    **Combinations** count ways to choose items where order *doesn't* matter.
    Ex: Choosing 3 committee members from 10: C(10,3) = 10! / (3! * 7!).
    Pro-Tip: If rearranging selected items gives the *same* outcome, it's a combination!

    Which is why ten is such a bloody silly choice for a number system base. We should be using sixty and/or twelve!
    And don't get me started on our use of c/d instead of c/r to describe the fundamental circle constant!

    Voting is not just a matter of those who vote, but also of those who count.
    #GOP government attempts to prevent non-GOP citizens to be involved in #counting #votes in the #midterms. For transparency, citizens of all political backgrounds and affiliations must participate in the counting. If trump succeeds in manipulating the #midterms in his favour, the USA will cross another thin line towards #dictatorship. #nofascism

  8. Number #two has a very interesting #etymology: Despite the differences between two, #dva #doi and #zwei, they come from the same Proto-Indo-European root: dwóh₁.

  9. Why is it that we have so many #counting concepts up to 12 or 60 like hours/minutes/12 pence in a shilling?

    en.wikipedia.org/wiki/Duodecim gives a speculatively explanation: it's based on a different way of using our fingers to count.

    One thumb is an indicator that goes through all the 12 knuckle bones of the four larger fingers.

    The other hand uses all 5 #fingers to count the number of dozens which enables you to count up to 60.

    Seems a reasonable explanation to me.

  11. At the 1965 Pentathlon World Championships, veteran Austrian Herbert Poopenhuber was leading the competition until he missed the last event, forgetting there were five.

  13. In the process I also thought of a #binomial #coefficient interpretation for choosing k things out of a bag of n objects when the objects can be put back and picked again. In probability problems, this is referred to as picking "with replacement".

    Usually, when we say, n choose k, we do not allow repeated choices, every chosen object has to be chosen once. In this case, I want to allow replacements but at the same time, I want to keep using my trusted n choose k idea.

    Here's my way around this: We'll still be picking k things, but we'll pick them not from 1 to n but from the set {1, 2, ..., 𝑛, 𝑟₁, 𝑟₂, ..., 𝑟ₖ₋₁}. That is, in addition to the n objects, we add what I'm calling "replacement tokens" 𝑟ₓ. If any of the 𝑟ₓ gets picked, then it is interpreted as the 𝑥th choice was put back and you are now choosing to pick that again. Since the 𝑘th choice is not put back, we only need replacement tokens for choices 1 to k-1.

    With these replacement tokens, the problem becomes a standard choose k things out of this set, which we can resolve using the binomial coefficient to get: \({ n+k-1 \choose k }\).

    I believe the standard approach to this is via #StarsAndBars but I liked the idea of this "replacement token". Admittedly, I didn't want to use stars and bars here and made up some stuff which I happened to like. :)

  14. I don’t know why I am drawn to the calculation of these things. If it was an isolated case I wouldn’t worry, but I don’t seem able to do anything repetitive without a counting mechanism clicking on in my head.

  15. Received a request to share a short Hebrew lesson on counting numbers.

    Here it is Heather and tell your class I am thrilled to share Hebrew with them!

    Remember to scroll through my videos on here, I have many bite sized lessons perfect for any teaching occasion.

    #CountToTen #LearnHebrew #LanguageDevelopment #Counting

  16. ✨ Hebrew loves the number 3 ✨

    🔹 3 letters = endless words
    🔹 3-letter roots = meaning unlocked
    🔹 3 steps to speak Hebrew: hear it • say it • live it

    Hebrew isn’t memorized — it’s built 🇮🇱
    And once you get the 3… everything clicks ✡️
