Maths

I remember when I was at school (about 11 years ago now) and had forgotten my calculator for a maths lesson - I thought I'd try to use my initiative and work it out on paper instead but needed the teacher to go over a technique for me (I think it was long division or something) - the teacher flat out refused and told me to borrow a calculator. I guess the manual working-out stuff must be disappearing off the national curriculum...

Lol no it's not, it was in the original example, but I said I was ignoring the 6 x £6 vouchers as they didn't contribute to the example! I win!

Yea, its quite bad actualy. Eveyone reaches for the calculator nowadays, but what gets me is when its for something very simple, a simple sum you can do in your head if you just put a little effort in and think clearly for one moment.

It would be great to learn how to use a slide rule, just incase my calculator dies

I do need the logarithmic function alot though, so a scientific calculator is quite a must for me

Thats how a slide rule works, its a linear / logrithmic scale

Got mine in Boots, but that was in 1970.
Proably ebay best bet now!

Most pilot supplies shops will sell you a circular one, slide rule on one side and wind drift and speed calculations on the other, and even a scale to work out your Mach No.

Absolutely! I remember a few years ago, before full barcode zapping tills, I was buying a new rugby shirt and a couple of other bits and pieces. At the checkout I decided to add a new pair of socks. So £1.99 needed adding to the total. The assistant reached for a calculator, and promptly got the answer wrong! I politely suggested re-calculating, offering "add £2 and take off a penny", to which I got a blank look of total confusion.

Technology today is wonderful stuff, but most people seem to forget that garbage in still equals garbage out, however quickly and accurately it's been processed.
