How do you do long multiplication and division, with or without having a wisdom tooth pulled? I am just trying to understand. :-) With a pencil and paper, mostly. |

I said I didn't have instant recall on them, not that I couldn't do them and didn't use them. This 'discussion' is becoming silly. |

I like* things like '75% fat free' ... meaning 25% fat? Eyww. To digress, in California you can get egg-free omlettes and fat-free sour cream. I have a container of the latter, but couldn't figure out how to preserve and transport the former. |

Very true. But it would help if more than 20% of primary school teachers knew the answer to "what is one plus two time three". In my highly scientific survey of teachers at schools that my daughter might have gone to 15 years ago: - about 50% were convinced the answer is 9 - about 30% asked where the brackets were, and were stumped when I said "none, just the normal laws of arithmetic" - about 20% got the right answer It would also be nice not to have secondary school teachers tell me that I couldn't possibly have elementary calculus for O-level (and a year early at that, just like everyone else in my state school) |

: I went to a Private School and they were very hot on the 3 x 'R's from a very early age. Later, and as I had no desire to go into the Hotel business like my parents, I went for an interview for an Apprenticeship as a Marine Electrical Engineer During the interview I was asked 'What are your Maths like?' 'Good I suppose', 'What are 7 x 8's?' and before he had finished I flashed '56'. I always remember that because I surprised myself as to just how fast I was able to recall it!!!! That's arithmetic, not maths. (OK, a small subset of maths) |

: Arguably, knowing ones tables is a lot less important than being able to understand percentages, differentials and probabilities. Often I see articles in the press in which percentages have been translated into fractions which are plain incorrect, hear people mix up "RPI is lower" with "prices are reducing", or see people worry unduly about a "50% increased risk" when the risk itself is so small that the change in behaviour to avoid the risk itself has more ill effects! I'd happily settle for less ability to multiply numbers together in ones head in exchange for greater understanding of what the numbers actually say, and therefore a greater ability to separate scientific argument from opinion and quackery. One of my pet peeves is the statements that you can reduce your consumption of X by 900%, where X is fuel or jelly babies or whatever |

: In real life being able to instantly recall a product is better than knowing how to derive it from scratch. And much better than either is knowing how and when to use/apply it, and to use the right tool to get the correct answer. |

Worked and continues to work, for me. The difference between our generation and the young ones, is that we can do mental arithmetic. Tables are part of the basic tools needed to do this. Not necessarily. I didn't rely on them and still don't. When my elder daughter had trouble with her tables, I taught her the methods I used and said that I didn't give a damn how she got the answer, provided that she got the right one in under a second. She did, and got a first-class engineering degree. There's more than one way to kill a cat. Nick says people can use a calculator, but I have yet to see anybody doing this in a supermarket, for example. Our two kids did arithmetic using a calculator at school. I don't think they even own one nowadays. If you can't learn tables and can't learn the mathematical tricks, then any sane person would buy one. Regards, Nick Maclaren. |

It's no great encumberance to learn the times table at an early age - it can only help in future years. There maybe more than one way to skin a cat, but it doesn't hurt to have more than one string to your bow. Children at the age that times tables were taught could readily absorb the information, why deny them such a wonderful experience of learning a technique that could serve them well in their future lives. When you know what things mean mathematically, calculators are fine ( they save time, and time is money), but, same as GPS they're ok while the batteries still work. Bill |
