Believe it or not they are taught those tricks about calling £1.99 £2 and then taking off the extra.The 'calculator generation' don't need to know these tricks. That is how shops get away with pricing like one DIY store tried on, they sold one length of timber for £1.99 and a pack of ten for £19.99. Shop assistants aren't very good with the 'residuals', we 'older' customers ignore the 'penny off' and round up to the 'true' cost (1.99 is nearer 2 than 1!) and then subtract the pennies. It is quite painful watching them do 1.99 + 2.99 + 1.99 + 0.99 rather than 2 + 3 + 2 + 1 - 4p
I still do that round up then subtract of course I'm no longer allowed in TescoBelieve it or not they are taught those tricks about calling £1.99 £2 and then taking off the extra.
I have heard rumours that the teaching of arithmetic has changed in recent years and the skill of estimation is being encouraged, however a) there must be at least one calculator generation that wasn't taught, and b) I am convinced that the majority of pupils learn enough to pass exams but totally fail to realise that some of it has application once they have left school!Believe it or not they are taught those tricks about calling £1.99 £2 and then taking off the extra.
A little off topic but my wife has been in the hospital a couple of times in the last week and they weighed her and gave the weight in kilo'sJust a quick enlightening joke. A tramp goes into a posh restaurant, enjoys his meal and asks for the bill. This comes to 10 shillings and six pence. The tramp says to the waiter " 10 and six are sixteen, sixteen pence is one and four, one and four is five, her's a tanner, keep the change. As an aside, even today when asked the weight of their new born baby 99% of folk give the answer in lbs and ozs.
While I can quite happily do the metric arithmetic, I still can't envisage what much of the metric stuff looks like. For instance, it is 13 km from my house to Istron where my friend lives. I still have no idea what 13 km looks like - I have to do a quick multiply by 5 over 8 to get it to miles to visualise that!
Bob, what is interesting as you know all of the cars built in the US are metric even the domestics are built to metric standards. The hospitals are now following in part because most of the pharmaceuticals are metric!A little off topic but my wife has been in the hospital a couple of times in the last week and they weighed her and gave the weight in kilo's
No one here in America knows a thing about the metric system I could go on
I found this article interesting and guess as school kids we must have been presented with the same problems with our maths.When I was growing up I did not have any problems with the complexity of the old money. The most I had to deal with was a shilling, never had much more than that until I was 12
