Quora is an amazing community of educators. I joined Oct 2019, two years ago. My entries and comments on English and math and a little bit on other subjects have passed the 10,000 mark in terms of views. Hard to believe. Well, learners are allowed to contribute. This learner has blogged entries from Quora experts and used their answers in lesson plans. One contributor to science received 2,429 upvotes on a single post; so, my milestone is not remarkable.

An interesting piece of maths: Take the number 142,857 and multiplicate it with 2, 3, 4, 5 and 6, and see what will happen... 11/11/2021 01:01:03 pm
285,714; 428,571; 571,428; 714,285; 857,142 --- the digits in every answer are the same digits in the original number, just arranged differently - fantastic 11/11/2021 01:16:44 pm
and the original number when multiplied by six switches the place value of the two groups of three consecutive digits, and there are six digits in the original number
