Description
Professor Mike Pentz, Dean of Science, introduces the programme with some remarks about the relationship between the four television programmes and the printed texts in the Preparatory Maths packag...e. The main part of the programme illustrates some ideas about numbers - positive and negative numbers, decimal numbers and powers of ten. The addition and sutraction of positive and negative numbers is illustrated with a dice throwing game played by the presenters, Mike Pentz and Allan Solomon. After a brief reminder that the decimal notation for writing pounds and pence can be generalised and extemded for very large or very small numbers a more convenien way of writing numbers is investigated using powers of ten. The number of water molecules in a bucket can then be written succintly as 1026 rather than a 1 followed by 26 noughts, and negative powers of ten can be used for representing very small numbers. The programme is linked to printed teaching material containing more examples of manipulating numbers of all kinds.
