You are in a shop, and you see a snazzy pair of jeans for £97.
You have no money on you though, so you borrow £50 from person 1 and £50 from person 2.
You are left with £3, so you give £1 to person 1, and £1 to person 2 and you keep £1.
So you owe your two friends in total 49 x 2 = £98
You have £1 so that's £99.
So where has the other pound gone...?
