TODAY'S #dailymaths MATHEMATICS 2020 CHALLENGE PROBLEM (in pic). Each day's problem (w/previous day's solution) is tweeted ~6am Eastern. If you, your child, or your students would like to join our mathematical community by doing a guest solution, please DM. We'd love to have you! 
Yesterday's problem and solution. I'm so excited!!! Nothing makes me happier than the days when we get to learn some real mathematics and not just show off which one of us can be the biggest pedant!!! Our guest mathematician is the coolest account on this site, @drrollergator!!
Abstract Algebra is usually not learned until post-calculus at university, but guess what? This is totally unnecessary! With an excellent teacher, even kids can understand it, and @drrollergator is here to give us a primer on the field that was basically invented by Emmy Noether.
This answer is long but well worth it--FEAST, FEAST CHILDREN on a beautiful explanation of abstract algebra!
Thank you, @drrollergator! Emmy Noether thanks you from the past and we thank you today. 🥰
