Question:
What are the real life usages of integers? Also what is the origin of integers?



Hi Travis,

Your question we have received before and we have two replies, one by me and another by Penny.

Your second question is much more interesting. Research by psychologists has shown that babies, as young as three or four days old, can tell the difference between collections of two and three items. By four and a half months of age they can tell that one plus one is two. Some animals also can estimate small integers and do simple arithmetic. So what is the origin of integers? It seems that, at least the first three positive integers, are with us at birth.
