I use Google Chrome on Windows 11, currently. I like to make web pages to test out different experiments/projects for fun. I know HTML5, CSS, and JS very well. I know Java and C to a good degree. For those who played around on their TI-83s & TI-84s, I'm very good at TI-BASIC. And that's about it when it comes to programming!
In regards to Mathematics, I have taken up to Calc II and Linear Algebra in college and have a very good understanding of the basics of Calculus. Integrals and derivatives I can deal with; first and second order differential equations and anything more advanced is where I draw the line. So, basically I can only remember like half of Calc II, and most of Calc I.
