This course covers the maths behind how your computer stores and manipulates data. You'll learn how to read binary and hexadecimal, how both integers and floating point numbers are stored and the limitations of using them. Advice on best practices and how to work effectively with boolean values and bitwise operators.

Have you ever wondered exactly why displaying the contents of memory often gives strange-looking numbers like 0x38FF that contain letters? Or puzzled over a time when your code added two floating point numbers but the result wasn't quite correct? If so, then this is the course for you.
This course aims to teach you the mathematics behind how computers store and manipulate numbers and booleans. You'll learn, amongst other things:
In this course you will learn about:
Binary is a number system made up of only 0s and 1s, which represent "off" or "on" respectively. This allows numbers to be represented physically inside the computer, which makes it possible for the device to perform calculation. Binary is used to write data, like instructions for the computer processor.
Hexadecimal, or hex, is a number system that uses 16 as its base, rather than 10. Rather than just using the digits 0-9, it also uses letters A-F to represent values of ten to fifteen. Hexadecimal simplifies how binary is represented, so an 8-bit binary number becomes a 2-digit hex number.
This course is for anyone who wants to learn the mathematics behind how computers store and manipulate numbers and booleans! It is also great if you are trying to learn how to read binary and hexadecimal numbers.
There are no strict prerequisites to this course, but it is intermediate level material, so come prepared to exercise those mental muscles!
