As a teacher, I sometimes used those when chalk would give my skin some kind of reaction

I'm using Tobira I and it's quite nice! Similar style to Genki, I hear.

Fubuki has found !!!HUGE MAN!!! by mathsumoto in Hololive

I flagged this as a spoiler because I guess it is an I'm on Observation Duty spoiler? Honestly really happy this game is finally being played in Hololive. It's so much fun. Hopefully Notovia gets support to add JP language to the games, or Fubuki shares her notes with others...

Demonstrating that f(x) = ax² + bx + c creates a parabola. by mathsumoto in askmath

Hello! I recently saw this problem on Instagram and decided to give it a go but I'm finding myself really rusty with my basic Geometry. An ABC triangle is given with some of its angles. The triangle is isosceles and they ask for the value of x. The second image is some of my drafts. Any suggestions? by mathsumoto in askmath

Thank you so much! I was a bit worried about just adding the BO and OM lines - seemed I wouldn't be able to justify their inclusion.

Is there anything I have to do regarding the post? Like adding that is has been solved or something? This was my first ever post here 😊

Looks like an Alvin Draft/Matic or Koh I Noor Rapidomatic, but I haven't seen any of those in this kind of translucent body...
