    I just remembered that I posted this. Thanks, DM - I think I sort of understand it. I don't think I'll try explaining it to my wee class.

    That's neat. The grid method with having to multiply.
    Bit of a pain for doing 89 x 97 though!
     
  4. I only came across this 6 months ago..it's creating column headings. It isn't worth showing to middle or low ability as they need to get their heads around the methods already shown, but cn be useful for the top end.
    Good post!
