If you watched the recent Horizon programme on BBC Two â€“ 31 March at 9pm to be precise â€“ you canâ€™t have failed to have been moved by the power of maths and how we are literally surrounded by myriad aspects of it in our daily lives. Professor Marcus du Santoy, an Oxford mathematician led Alan Davies, comedian, through a series of interesting exercises to help him conceptualise how we assess probability, angles, and one, two, three and four spatial dimensions.
Professor du Santoyâ€™s enthusiasm for his subject was infectious. Maths is fundamental. We use it constantly whether we are aware of it or not. It helps us make good, rational decisions. And yet, how many of us are confident about expressing numbers in print? At first sight this may look amazingly straightforward but recent courses have revealed that lots of delegates are unsure when to use figures or words to express numbers. And many fudge a perfectly good point by using â€śa number ofâ€ť rather than the exact amount.
