Thinking involving very large and very small quantities
Intuitively a million is a lot more like a billion than ten is like one hundred, because our intuition has some grasp of ten and one hundred, but we have little grasp of what millions and billions involve. Fortunately, there is often a way to make intelligent decisions involving big quantities. Use arithmetic! Typically we don't need more than multiplication and division to put things into terms we can deal with. If we are unwilling or unable to do the calculations, we should at least recog
