I posted last Tuesday (I think) - the 20th, with a maths homework question of ds1's. Marina answered, amongst other people. I cannot find it anywhere - have checked my threads, Marina's threads...key words. Where's it gone?
The title was something like... need help with maths homework quick please, and in the text of the post I said I was a self-confessed maths divvie. I need to know the maths question itself.
Sorry to be cryptic - will post why I need this if ever it turns up!
