In TM 112 you continue to develop the basic mathematical skills that are part of computer science. You have the same Using Numbers site you used for TM 111 and will get plenty of guidance on particular topics in the module units.
TM 111 introduced the basics of binary representation, but the way data is stored and processed inside a computer involves more advanced binary representation, including concepts like two's complement notation and floating point notation. You will learn about these topics in TM 112. but we assume you are famillar with the basic binary notation topics covered in TM 111. So if necessary, take a quick refresher course using the drag and drop game we used in TM 111.
Similarly, when studying a technical or scientific topic you need to be really confident about the use of scientific notation and rounding. It is not enough to understand it: you need to be so used to it that you can take it in your stride, and concentrate on the topic it is describing. Again, if you need a reminder, there is a quick demo in the pages below.
In Week 1 of TM 112 you extend your study of binary representation to include fractional numbers, negative numbers and floating point numbers.
1.1.4 covers the two's complement method of representing negative numbers
1.2.1 covers the representation of fractional values, including floating point representation
Before studying 1.1.4 be sure you recall the basic binary notation learned in TM 111
Before studying 1.2.1 be sure you have a good understanding of scientific notation
