I loved tixy when I first discovered it a few years ago so created this https://www.mathsuniverse.com/tixy (with permission from the original author) with puzzles to solve on the tixy grid. I use it with my computer science students who get really into it.

Reminds me of [Replicube](https://store.steampowered.com/app/3401490/Replicube/), which has released recently and does the same kind of thing in 3D.

This is a cool way to teach!

I was blown away by the little functions at first and I too made a clone to experiment with calculang [1].

I added an evaluation feature (F9) so you can select sub-expressions and see what they do, which was helpful to figure out some patterns (video in [2])

I've been programming for over 40 years, and I can say this is the most fun way I've experienced to learn this kind of thing. It really is fun.

My 5yo did great on these until he hit #7 and got stuck! I’m helping him with syntax but trying to hold back from giving conceptual hints for now.

I love the instant visual feedback!

Why isn't "(sin(i) * (x > 7)) - (i == 5) + (i == 20) + 0.5 * (i == 32)" a solution to puzzle 36?

Fun. Thanks!

Works well on phone. The phone keyboard is a bit clumsy but it works (that’s a phone issue)

Well done!

> In computer graphics, the origin (0, 0) is top-left rather than bottom-left

Umm...

What's wrong with that statement? It has historically and traditionally been true for raster displays, even if there do exist ways to use standard Cartesian-style coordinates with a computer.

I'm struggling to see the problem with this statement, other than maybe to add in the word "usually". My students will know of graphs in maths where the origin is always bottom left. When working with HTML canvas and every other computer graphics situation I've worked in, it's top left instead.
