What did you get for problem 2?

Hi MathsisFun;

For the introductory problem:

I have heard of the controversy surrounding 45 000 000 000. I want you to know I do not favor the extremists who believe there is an integer larger than it.

I don't know about you but the problem before number 2, n^2 + 9 + 9 is amazing. That's a great toaster too,

I got a different answer to problem 3 but sorry that 8 pence answer totally beat me.

Excellent video!
