Why Should You Learn About Algebra? [2:34]

"We've all been there sitting in a maths classroom, wondering what the point of it all is. Well, Dr Hannah Fry, mathematician, is here to tell you why algebra matters."

Basic Algebra Lessons for Dummies/Beginners [15:17]

"Easiest way to Master Algebra without even learning anything math. Go to and get the complete course and more. Follow the steps and get the answer. (DUMMY PROOF). Can be used for Pre-Algebra"

The Basic Idea of Calculus [3:07]

"If you are wondering what Calculus is, or what your teacher was ranting on about, this is a quick look at the basic idea behind it all.
The next part is here: Don't worry, I'm still going to make Quantum mechanics videos too :)"


  1. Welcome to Geometry [1:40]
    "Are you ready to learn geometry? We introduce you to the main themes we will talk about in our series of videos. It's always good to know where you are going before you begin your journey..."
  2. Sum of the Angles in a Triangle [1:18]
    "We prove that the sum of the angles of any triangle is 180°. The proof is short and sweet. It is important to develop the skill of proving things, because when you understand *why* something works, it reinforces your knowledge."
  3. Area of a Triangle [1:37]
    "We introduce the formula for finding the area of a triangle - how any side can be used as the base. We show you how to handle units, and demonstrate how you can change the perimeter but leave the area unchanged."
  4. Quadrilaterals, an Overview [2:30]
    "A quadrilateral is a four-sided polygon. There are lots of different names you can use to describe quadrilaterals, and in this video we describe 5 specific terms: rhombus, rectangle, square, trapezoid and parallelogram. Outside of the United States, the trapezoid is better known as the trapezium."
  5. Introduction to Polygons [2:24]
    "Learn the definition of polygon - a very important shape in geometry. When a polygon has a small number of sides, there is a word you use instead of "polygon". We teach you the names of polygons with 3 to 10 sides."
  6. Introduction to Angles Using Degrees [2:36]
    "The two most common ways to measure angles are degrees and radians. In this video, we introduce the idea of angles and how to measure them using degrees. We also talk about common terms to describe the size of angles: acute, right, obtuse and straight angles."
  7. Complementary, Supplementary, and Vertical Angles [3:13]
    "How do you talk about pairs of angles? The three most common terms are vertical, complementary and supplementary angles. In this video we cover all three types and give several examples."
  8. Parallel Lines and Transversals [2:15]
    "Two lines in a plane that never cross are called parallel lines. Any line which crosses both of the parallel lines is called a transversal. In this video we talk about corresponding angles and vertical angles formed by a transversal. It's important to remember that these results are for Euclidean geometry."
  9. How Do You Find the Center of a Circle? [4:13]
    "One classic way to find the center of a circle is to draw two, non-parallel chords, then construct their perpendicular bisectors. They will intersect in one point - the center of the circle! This technique works even if you do not know the radius or any of the points on the circle."
  10. Introduction to the Pythagorean Theorem [4:03]
    "The Pythagorean Theorem says that for any right triangle, a^2+b^2=c^2. This means if you know two of the sides, you can solve a basic equation to find the length of the third side."
  11. Pythagorean Theorem Proof [4:09]
    "The Pythagorean Theorem says that for any right triangle, a^2+b^2=c^2. In this video we prove that this is true. There are many different proofs, but we chose one that gives a delightful visual explanation for why the Pythagorean Theorem works."

Chemistry Success [6:45]

"Chemistry help video from HACC Office of Academic Success."

Introduction to Physics - Studi Physics [3:39]

"I'm sure you've heard about Physics before. Some people say it's hard, other people say you have to study it if you want to be an engineer or a doctor. But Physics is actually way simpler than what you might think. The word physics comes from the Greek words Phusis, which means nature and Phusike, which means knowledge of nature."
