Scientific Calculator

Are you bored with just adding and subtracting numbers? Do multiplication and division make your head swim? Are you one of those people who still have nightmares about math class? Or are you a dedicated number-cruncher looking for a challenge? If any of those apply to you, then you could benefit greatly from a scientific calculator. After all, they're not just for nerds with glasses and anoraks! Forget the boring math you had to do at school, with its log tables and fractions. Forget the nightmarish trigonometry problems. With a scientific calculator you can do what seemed to be even the most long, complicated task with merely a couple of button-presses. Can you remember having to roughly ‘guess’ square roots as a child? Not anymore -- just enter your number, hit the button, and it's there. A cube root? Easy as Pi. Do you remember having to look up natural logarithms in a battered old book? Now you just whack it in, press the button, and you're away. The first electronic calculators were often driven by LED displays that simply ate batteries; now, scientific calculators are all LCDs, cutting battery replacement by a factor of ten, but many of them have huge displays that will display all manner of goodies such as graphs. Yes, you can add up your weekly grocery bill using a calculator, but just trawl the Internet for sites that will help you revise your maths, and you'll be completely captivated by some of the stuff you can work out with a scientific calculator.
