I want to find a website where I can learn all about math, pre algebra, algebra, calculus, geometry, statistics… everything
I need it to be free since what I’ve encountered online needs a subscription
Context: early 20s, current academic level is Master’s in a scientific field
Reasoning: math has always been a little bit scary for me and I want to start from the very beginning in order to feel more confident, id love something interactive and not just lectures, getting to do exercises and placement tests etc
