Each week the Daily Mail comes with a Weekend supplement imaginatively named "Weekend".
At the back of this publication is a weekly quiz named "Homework for Grown ups" a quiz which I do each week and I'm lucky to break 5 out of 10 - once managed 8 but mostly get 3 to 4.
This week one of the questions really fried my noodle.
It is as follows:-
-4 x -8 =
a) 32
b) -4
c) -32
d) 4
The correct answer is a) 32.
I've read the mathmatical rules being this and I still don't get it, and I'm reasonably good with maths generally!
How can multiplying two negatives produce a positive?
BTW I answered c) -32
