I've got items to deliver and need to figure how to use the least number of stamps.

eg 34x +24y + z = 289

all of the unknowns have to integers.

also if anyone could write this mathematically correct I'd like to learn more about this topic.

thanks for any help

I heard it on QI something about when you add 2 and 2 using log it turns out to be 3.99 recurring.

I heard somewhere this was true.

Is that an impression of Steve Irwin?

oh. and I nearly forgot Paul Hogan.

kangaroos I suppose.

oh I see. So all the t's don't count because they're suppose to be little anyway.

He hasn't died because I haven't seen episode 4, 5 and 6 so his death is only a speculative rumour.

You counted?

Glad to be welcomed.

Didn't you answer your own question "Fun in Mathematics" prize.

Me. Enough about me how about you.

wait let me refresh. Yep it would.

I'm really confused what does

◊0=0

◊1=1

mean?

I only started a level is there a easier way? I think I saw "S=n/2[2a + (n-1)d]" when the teacher did it.

thanks, JD

Could someone help I'm not sure how to do this.

"Show that the sum of the first 2n natural numbers is n(2n+1)"

It's a question from the heinemann c1 book.

I would ask the teacher again but it's half term and I don't know his phone number.

good day
