the internet is currently fascinated with #Cistercian numerals.As a fan of chocolate-making monks and of weird glyphs, I approve.This also gave me the chance to explain to my kids why indo-arabic numerals are cool: they saw the easy numbers up to 9999, and then I asked them: how do you represent 100000?And yeah, there's "non-standard extensions" to Cistercian numerals, which need to be accepted and known by everyone . But it's much better to have a zero.#numbers #parenting
