# Thread: How times of changed

1. ## How times of changed

or - old fogey time.

I got an email from Staples today advertising (amongst other things) a calculator

http://www.staples.co.uk/printers-sh...DD-I5HHYK-MFTY

Made me think. In 1972/3 a colleague bought a Sinclair calculator which cost ~ £90 (~ £1000 today) and could only do 4 functions. And it tried to divide by 0 when asked (you could see the display turning over). I bought a calculator (not Sinclair!) in the late 70s; this had more functions and gave an error when you divided by 0. I think the cost was about £20 (~£100 today).

Now this one for £5, sigh.

And no lines like 'in my day we were lucky to have a slide rule' or 'in my day we were lucky to have pencil and paper'

2. Quite recently you used to be able to get a Tesco "Value" four-function calculator for 64p ~= \$1.

Anyway, dividing by 0 is not a good test of a calculator:
do 1 ÷ 7 * 7 = and be unimpressed when the answer comes out at 0.99999997 and not exactly 1...

3. In my youth I bought an Abacus that cost more then the most advanced calculator made today.

At least the Abacus didn't need batteries.

You'll have to help me here, being from the UK! How much do things usually cost in a dollar store?

6. Items are supposed to cost no more then a dollar.
Believe me, it's like burning money.
Whatever you buy there falls apart while you are carrying it out to your car.

Most of the stuff, if it food or candy has long expired..

I bought a sponge there once and it just about dissolved the first time I used it.
