E52:What is the value of mathematics?

The minimal objective in schools in most countries is to ensure that leavers, somewhere in their teens, are both literate and numerate. And while teaching methods have changed and in some ways advanced in recent decades, where the traditional approach has been totally abandoned, far too many pupils leave school innumerate. Numeracy may be defined as the ability to carry out elementary tasks under the three headings-arithmetic, geometry and algebra. Of these, arithmetic is the most valuable for ordinary purposes.

If that is true, it is something of an irony that electronics, which help mathematical processes in so many directions, have had an adverse effect on pupils' ability to do mental arithmetic. Pocket calculators give immediate solutions to virtually all mathematical problems. In no way do they exercise the brain. So, the use of logarithms and the slide-rule has disappeared. The ideal situation is the teaching of mathematics by the old methods and the use of calculators for checking purposes only. Given the basics, a pupil can then use the calculator to great effect in the outside world.

So, what are the uses of mathematics to the ordinary person? As a wage-earner, it is an obvious advantage to be able to check one's wage slip and bring any discrepancies in deductions for tax, insurance, union dues etc to notice. Secondly, it is essential to be able to work out a personal budget, and if possible to allow for savings to cover holiday expenses, other luxuries, and unforeseen calls on the pocket. As a professional, self-employed or business person, further advantages emerge. Assume you wish to start a small business and you approach your bank manager for a starting loan. He or she will expect a realistic breakdown of initial costs, wage bills, if any, expected returns, with provision made for taxation, VAT if applicable, rent, leasehold or mortgage repayments, and of course the preparation and auditing of accounts. None of this is possible without at least an elementary knowledge of mathematics, and your manager will show no sympathy if you expect to pay somebody else to do the work.
