There is an error in the first example problem. 3^5 is calculated incorrectly (should be 243 instead of 273).

An explanation of how bases (ie: Base 10, Base 2 / Binary) work, how to convert between bases, and how to interpret numbers written in different bases.

- Lesson Slides - Slides that are written on from the lesson.
- Converting numbers between bases - A conversion calculator and table of example values to help understand other bases and change between them.

- What is a base?
- How do you change between bases?
- How do you write a number in base 2?
- How do you read a number in base 2?
- How do you write a number in binary?
- How do you read a number in binary?

A bottom-up approach to understanding bases other than base 10. It not only gives you a comprehensive understanding of what it means to have different bases, it also shows you practical examples and steps through how to convert numbers to different bases. A good lesson.

I like the explanation, but there was a math error in the first exercise explanation. 3 raised to the 5th power is not 273. It is 243. Oops! Nevertheless, I now understand the bases whereas I did not before watching this video, so thanks.
