Welcome, MathFour-ticians!

I’m not so sure what to do with Periscope, but I have it. So why not use it, right? I’m getting it down – and loving it!

My first attempt at periscoping is going to be a daily “Knick-knack Yack from the #MathShack!”

It’s going pretty well, so I’m rolling with it. I’ll be doing weekly recaps as posts, but here’s the running list, with the most current on top:
