Calculating all the 2-Digit Prime Numbers from scratch (and random math/nature chat)

Was gonna film this as a video about primes, but decided to film it live. After I generated the 2-digit primes, I chatted about "superior" highly composite numbers, "hollowelevens", cactus fruit, birds, and etc... Btw if it sounds extra noisy, that's because my neighbor's kids are having a party or something haha.

How do you go about finding all the patterns you show in your videos or is it just stuff you already heard about

17:02 Squirrel ! I bet he came for the lcm(1, 2, 3, 4, 5, 6, 7, 8, 9) = 2520

How about having the clocks go backwards? They'll be correct even more often!

This is pretty interesting. I had no idea what superior highly composite numbers even were.

I had to calculate all the 2 digit numbers in my middle school math team once. I knew the threes trick but when I had to cross out the sevens i just wrote out every multiple of 7 and crossed them off from there

I couldn't get over the background noise. Would love to watch again without that.
