Check out “Numbos”, an ode to Wordle. It will provide similar green/yellow hints, but beware: there may be duplicates and a yellow may indicate a green in the same guess. Two yellows may refer to the same position. desmos.com/calculator/veszac…

newest Walt's tricky math riddle: find the length of m (the diagonal) #waltsays #trickymathriddle
On a whiteboard with purple marker, an 8-year old has drawn a square with side length n. circle inside n-length square contains a second square. there are four diagonal lines (m) connecting the inside square with the n-length square. "Find m."

Any Die Hard 3 fans will recognize this problem. How can you get exactly 4 gallons using only a 3-gallon jug and a 5-gallon container? Here’s Walt’s solution.

Here’s his code (he was introduced to this type of problem by way of a puzzle game app that used 9, 5 gallon buckets to get 3 gallons)

Me: Bring your sheet over here so I can take a pic Walt: It’s a Google DOC, not a sheet 😂 #waltsays (This is his proof of why zero factorial equals one. Corrections welcome…I certainly can’t offer any. -e)

Walt had a great 8th birthday yesterday! If you get the candles joke, you’re in the right place.

And Horrible Histories and Hey Duggee and Maddie’s shows and Mr Tumble and Number blocks. And for that matter, David Attenborough and Lucy Worsley and Brian Cox and David Olusoga and so so many others. There’s a reason they all came to us through public service broadcasting.

Happy new year! Is your head clear enough for a little math this morning? 🥴 If not, you can refer to Walt’s math notes.
A piece of yellow paper with child handwriting with the following equation in marker: Let f(x)=sin(x)/cos(x)-tan(x). What is f’(sin(x))? (Expressed in radians). To the right of the paper is a teal notebook. The cover has a handwritten, in child handwriting, label that says “Walt’s Math notes”

The same piece of yellow paper and formula as described in the first photo. The notebook is now open to a two page spread of child-written “Derivative rules”
