Hi there - John you say:

"when my Dad first used his calculator I found him adding the figures on a paper bag just to make sure the gadget".

I still do and I am younger than you let alone your Dad!

When I left school, before calculators, I worked in an insurance office and we had to add up long columns of figures all the time. I could even add one up upside down if I was sat opposite someone who was adding one up if it wasn't too long. I can never trust that I have keyed in the correct amount into a calculator!!!

As far as charging batteries is concerned. Wouldn't it be great if we could plug ourselves in and give our own personal battery a boost? I think mine have nearly reached their sell by date........Joan
