@CancionLogica @sonukg4india Oh, or is it defined as the number whose square is -1?

[Jack Lyons @LyonsMath]

@CancionLogica @sonukg4india i does not equal sqrt(-1)? I thought that was how it is defined

Hi teachers! What are your favorite math games for middle schoolers? So far I have: Prime Climb, Set, 24

@rsnbrgr @Digits_Analysis @Virion00 My students LOVED those puzzles. Bummed they are going to disappear

[Jack Lyons @LyonsMath]

@fawnpnguyen @Mrs_CHibbard Ahhh. Duh

[Jack Lyons @LyonsMath]

@Digits_Analysis @Virion00 @rsnbrgr Is there a similar app that someone created?

[Jack Lyons @LyonsMath]

@fawnpnguyen @Mrs_CHibbard Hmmm… not seeing it. Working backward, 5 times 319.2 is 1596, and that’s twenty-one 76’s. But why 76 x 21?

@MH_Binky @jamestanton I’d say stopping at two rolls is more likely than stopping at one roll. Depends on the prompt the rollers are given. “Roll these dice as many times as you want and add up the total as you go” will lead to very few <3 rolls, but people rolling just once seems less likely.

@NYTGames @nytimes Great game. Going to introduce it to my 6th grade students. Is there always a solution that uses all 6 numbers?

[Jack Lyons @LyonsMath]

@rhymeswspecimen Uh what school, cuz I had a very similar experience with my abstract algebra teacher.

I love math. I teach math. But let’s face it, some math teachers suck spectacularly. Exclusionism is deeply rooted in college mathematics.

@howie_hua If you want to remember how difficult learning the long division algorithm is, try using it in base 12! Reminds me of flipping the guitar around to play it the other way.

[Jack Lyons @LyonsMath]

@NYTGames hi! I saw the note that there will not be digital versions of the acrostic and variety puzzles starting 3/1. Does that mean subscribers will no longer have access to the archives, or that no new puzzles will be put online?

[Jack Lyons @LyonsMath]

@Daily_Epsilon Found the answer, then laughed. It was right there at the top!!!

[Jack Lyons @LyonsMath]

@howie_hua Kind of a weird one, but I immediately saw the 5’s as on die.

[Jack Lyons @LyonsMath]

@micmolymaths @MathigonOrg What are those diagrams?

[Jack Lyons @LyonsMath]

@FryRsquared I’ll go Change is the Only Constant @benorlin

This is a banner with names of children who died at residential schools. It is so long, it takes about three dozen people to march it.

@CmonMattTHINK Maybe it was a mural of a fractal on a concrete wall with cracks. Such a great song
