hi welcome to Learning Algebra from Scratch a course from UltimateAlgebra.com Addition and Subtractions in Algebra we can only add things if the letters and their exponents following them are exactly the same Example: we can add 2x + 3x because they both have X following the numbers All you do is add the numbers […]

## But what is a Neural Network? | Deep learning, chapter 1

This is a three. It’s sloppily written and rendered at an extremely low resolution of 28 by 28 pixels. But your brain has no trouble recognizing it as a three and I want you to take a moment to appreciate How crazy it is that brains can do this so effortlessly? I mean this this […]

## Times Tables, Mandelbrot and the Heart of Mathematics

ok so to start off I’ve got 4 images for you. Quick question what do all of them have in common. Well, I would be very surprised if you guess this one here. (Giuseppe) They are full of lines. (M) They are full of lines, they are in a circle. But actually they are pictures […]

## Cyclic Groups (Abstract Algebra)

We say a group G is a cyclic group if it can be generated by a single element. To understand this definition and notation, we must first explain what it means for a group to be generated by an element. Once we’ve done that, we’ll give several examples, explain why the word “cyclic” was chosen […]

## This problem seems hard, then it doesn’t, but it really is

Every year, more than 100 countries send 6 of their brightest teenagers, or the occasional pre-pubescent prodigy, to represent them in the International Math Olympiad, commonly known as the IMO. Considering that each country has its own elaborate system of contests leading to their choice of 6 representatives, the IMO stands as the culminating symbol […]

## Coding Math: Episode 21 – Bitmap Collision Detection

This is Coding Math Episode 21, Bitmap Collision Detection. A while back, we covered various forms of collision detection, and I believe I made a promise to cover collision detection with bitmaps at some point in the future. Well, the future is now. First of all, what exactly is a bitmap? At its most basic, […]

## How to Make an Image Classifier – Intro to Deep Learning #6

How do we classify things? We consider people to be experts in a field if they’ve mastered classification. Doctors can classify between a good blood sample, and a bad one. Photographers can classify if their latest shot was beautiful, or not. Musicians can classify what sounds good, and what doesn’t, in a piece of music. […]

## Math isn’t hard, it’s a language | Randy Palisoc | TEDxManhattanBeach

Translator: Radu Chirila Reviewer: Ariana Bleau Lugo 26% on the nation’s report card, that’s the percentage of U.S. 12th graders who are proficient in Math. In America, we pride ourselves as being an exceptional country. But does 26% sound exceptional to you? Raise your hand if you think as a country we need to do […]

## The RSA Encryption Algorithm (1 of 2: Computing an Example)

I have to kind of apologize. [I] thought about how to do this, right? I could have done this with actual How the Irsa system would actually work with actual numbers? With an actual like long message and all that kind of thing and we could do with computers I could show you how to […]

## Coding Math: Episode 27 – Easing and Tweening

Welcome back to Coding Math! I haven’t put out any episodes in a few months due to other commitments. Actually, one of the biggest commitments I had was creating a full video-based course on basic JavaScript for another company. This was a direct result of this whole series, I’m happy to say. The course, called […]
