Lesson Feedback


This video aims to explain counting systems (Decimal, Binary, and Hexadecimal). Students will get to know how to convert numbers between these systems. Also, students will learn how to do some byte and bit level operations. They will use a Visual Basic application that changes colors through logical operation on numbers. This lesson is especially useful for those who want to watch and learn from the MIT BLOSSOMS lesson, "The Magic Picture: Steganography in Bitmap Files".  A prerequisite to this lesson is simply the knowledge to use basic operations in mathematics (+, - , * , / , Power).  Needed for the lesson is a scientific calculator, or a calculator program that is a Windows accessory.  One could also add letters and numbers of children games to make some fun in the lesson! Finally, there is a Mixer, which is a simple VB application that I wrote for changing colors through logical operation on numbers. You can find it at the end of this summary.
