Answers on a post-card.
If you're wondering why I'm putting in a mathematical challenge see blog entry below.
The weird thing is I worked it out & got the right answer but then thought my working out was wrong & still can't see why it isn't wrong & have looked up the solution & the explanation for the solution & can't understand it. But it's ok because I'm not going in for the Maths challenge.
