I've taken up to Calculus 1 in college but that was a few years ago and haven't touched math since I still remember things but not as good as it was when I was taking classes a while back.<p>I want to learn and understand math everything from Fractions, ratios to Algebra being able to make sense of the world and understand math the big picture. I wanna know how to use variables to solve for unknowns in word problems any word problem understand the concept of math.<p>How would you go about this? books, videos or websites much appreciated.

Start with a refresher on calculus -- MIT's "Big Picture Calculus" video series is designed precisely for this: <a href="https://news.ycombinator.com/item?id=13634476" rel="nofollow">https://news.ycombinator.com/item?id=13634476</a><p>To develop your visual intuition, watch 3Blue1Brown's YouTube channel (he also has an "Elements of Calculus" series coming soon): <a href="https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw" rel="nofollow">https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw</a><p>Try to find the geometrical underpinning for each topic you learn. This will not only help you visualize what you're learning, but it will also help keep a red thread going as you traverse from topic to topic.<p>After calc, I would study Linear Algebra next since it's at the heart of numerical computing today, see: <a href="https://news.ycombinator.com/item?id=13620871" rel="nofollow">https://news.ycombinator.com/item?id=13620871</a> (note the comments, they also include many good pointers and references, e.g. here's a list of video's that help you visualize <a href="https://news.ycombinator.com/item?id=13623711" rel="nofollow">https://news.ycombinator.com/item?id=13623711</a>).<p>The Numberphile channel is always good to keep your mind thinking in numbers: <a href="https://www.youtube.com/user/numberphile" rel="nofollow">https://www.youtube.com/user/numberphile</a><p>Also, you can go through my HN stories profile -- there are a ton of math-related links and discussions in there, such as this one: <a href="https://news.ycombinator.com/item?id=13631213" rel="nofollow">https://news.ycombinator.com/item?id=13631213</a><p>Explore math topics on WikiPedia, YouTube and online lectures from MIT/Stanford/Caltech/Berkeley etc.<p>Group theory comes up often: <a href="https://en.wikipedia.org/wiki/Group_theory" rel="nofollow">https://en.wikipedia.org/wiki/Group_theory</a><p>Set theory is at the root of everything: <a href="https://en.wikipedia.org/wiki/Set_(mathematics)" rel="nofollow">https://en.wikipedia.org/wiki/Set_(mathematics)</a><p>Pay close attention to the concept of intervals: <a href="https://en.wikipedia.org/wiki/Interval_(mathematics)" rel="nofollow">https://en.wikipedia.org/wiki/Interval_(mathematics)</a><p>Practice reading journal articles until you can start to understand the notation (this may take a while but persevere, the continual exposure will start building fluency).<p>Practice implementing the concepts you're learning in Python.<p>Ask questions on MathOverflow <a href="http://mathoverflow.net" rel="nofollow">http://mathoverflow.net</a>. Quora is also good: <a href="https://www.quora.com/" rel="nofollow">https://www.quora.com/</a><p>Get and read SICP and do the material for the online MIT SICP course (it's the all-time classic CS course, with a math bent):
