The Mathematics Tutorial Series

High School Mathematics

For the past three years, I have written several series of posts explaining different mathematical concepts in this blog.  This post summarizes the collection of all these posts.

I will pin this post in this blog’s sidebar and will be updating it each time a new series is written. We will call this page, the Mathematics Tutorial Series.

Area Tutorial Series

  1. Area Tutorial 1 – Introduction to the Concept of Area
  2. Area Tutorial 2 – Area of a Triangle
  3. Area Tutorial 3 – Area of a Parallelogram
  4. Area Tutorial 4 – Area of a Circle
  5. Area Tutorial 5 – Area of a Trapezoid

The Divisibility Series

  1. Divisibility by 2
  2. Divisibility by 4
  3. Divisibility by 5 and 10
  4. Divisibility by 3
  5. Divisibility by 7 and its Proof

Guest Post: Why Study Algebra

High School Algebra, High School Mathematics, Math in Real Life

Many students who begin learning Algebra and even the ones who have spent many years learning Algebra have a common question: Why study this? Where will this be used? Why are there letters like x, y, z used instead of numbers in Math?  In this article we will try to address this question.

algebra

We all directly or indirectly use Algebra in our everyday life and most of the times unknowingly. For those who have spent some years with algebra will find k \times xy too algebraic but immediately recognize  \frac{1}{2} \times b \times h as the formula for the area of a triangle. Though one can see that conceptually both the expressions are identical (with one constant and two variables) and algebraic, one instantly connects with the usefulness of an expression or a formula than its abstract counterpart. » Read more

TED Videos and Ideas Worth Spreading

Audio, Video and Animation, High School Mathematics, Teaching Tools

TED is a global set conferences which started in 1984 dedicated to disseminate  “ideas worth spreading.” TED which stands for Technology, Entertainment and Design is owned by Sapling Foundation, a private non-profit organization.


Now, what might interest you about TED are the free videos, many of which are  lectures about mathematics and technology. The video above is the lecture of famous mathematician Benoit Mandelbrot about the beauty and complexity of fractals. Most of these TED videos have transcripts that are also available for download.  

As of this writing, there are more than 900 TED videos or TedTalks in science, technology, entertainment, design, business, and global issues. These videos are under Creative Commons License, so you are allowed to repost and share them.
