Small thing but hey if you hear someone working through simple math out loud, please don't tease them about it unless you truly know it's welcome. Dyscalculia is like dyslexia with numbers, people who struggle with it frequently make simple math errors. These are often reduced if we say the numbers out loud. Cracks about whether someone can calculate a tip or do other everyday math in their head...it can feel very not funny, and increase anxiety (making the calculating harder).#Dyscalculia

Holy cats was not prepared for how positively this post would be received! A few years ago when I found out about dyscalculia (and my whole life clicked into place), no one knew what it was. Kinda blown away right now. :)

@hollie Good post. Boosted.Actually, it's not only people with dyscalculia who benefit from speaking aloud when dealing with difficult problems. Everyone does. People who refuse to do it for fear of looking silly are less effective problem-solvers than they could be. So don't feel self-conscious about doing it when it helps!

@CppGuy @hollieUse your fingers! I grew up with educators who would slap our hands (if they could) if we used our fingers to do math.Why?!?I've got ten digits that are awesome at keeping track of things, even though I'm pretty decent at math.Fingers are great! I encourage everyone who was ever shamed like I was about using their hands to count to unabashedly count on your fingers and toes.

@vincent @CppGuy @hollie I hope this isn't rude, but to bounce off your post, a few years ago I saw an article about using one hand to count to 12, which I found amazing.You use your thumb to point to the different joints of the fingers, with index tip being one, middle top being two, all the way to the joint closest to the hand on the little finger being 12.It also allows for the other hand to count multiples of 12 each time you "wrap round", but that requires more mental arithmetic.

@DuvetGecko @CppGuy @hollie The ancient near-eastern peoples of Babylon and Assyria used the joints on a hand for counting (thumb excluded), to give 12 per hand. Which is not coincidentally how many hours make up a half-day. A whole day is two hands of hours.

@vincent12=2*2*3So twelf has nice prime factors, what makes it pretty practicable as a packing unit and so on...@DuvetGecko @CppGuy @hollie @Selena

@hollie Appreciate the heads up; thank you (I wasn’t aware it was even a thing) :)

@aral @hollie Here’s me, unable to do mental arithmetics in spite of trying hard for nine years at school. Then we were allowed to use electronic calculators (those old-fashioned thingies before mobile phones existed) and suddenly I became good at maths! I began to really enjoy it even , and I loved algebra - maths with letters, woohoo! So dyscalculia doesn’t keep you from understanding the logic of maths, it just keeps you from crunching numbers 🙂

@wauz @DuvetGecko @CppGuy @hollie @Selena Not a coincidence that there are twelve inches in a foot, not ten!

@vincentWell, in germanic languages, there are the basic numbers 1 - 12.Language is kind of "fossile evidence".@DuvetGecko @CppGuy @hollie @Selena

@wauzI love how "eleven" and "twelve" are from "one left", and "two left" respectively. Like, Germanic tribes ran out of fingers when they met Arabian tradespeople who were still counting.@vincent @DuvetGecko @CppGuy @hollie @Selena
