Today the BBC is telling us that "Poor numeracy blights the economy and ruins lives" That's as maybe. (See examples below) What annoys me is how articles like this refer to "maths" when they mean "arithmetic." Arithmetic is to maths as paintbrushes are to a J.M.W.Turner sunset. Now FTSE dismounts hobbyhorse to ask . . .
. . . 3 questions. Do they test your ability at maths, your ability at arithmetic or simply your ability to think?
1. If I tell you the average of two numbers and one of the numbers, can you work out the second number? (Example: Average of two numbers is 12. One of them is 8. What is the other number?)
2. The National Lottery asks you to choose 6 numbers from 49. What's the chance you choose the first number i) correctly, ii) incorrectly? And the second number . . . and so on down to your 6th. choice.
3. How many different four digit PIN numbers are there -
i) If duplicated digits are allowed?
ii) If duplicated digits are not allowed?
i) If duplicated digits are allowed?
ii) If duplicated digits are not allowed?
The words 'fun' and 'numbers' have never joined in my world...The concept is practically earth shattering, as the only hand in glove link-word to 'numbers' for me, is 'horror'.
ReplyDeleteBut I'd endorse the distinction between 'maths' and arithmetic' and agree, Geometry and Algebra have a fascination all their own, but that is because of what they can achieve, not simply because they use the dreaded 'numbers'....
But simply PLAYING with numbers for FUN? Ugh! Not on your Nelly - or my Ada, come to that.
I don't even count my chickens...
