Numbers are all around us, and they help us in many ways. We don’t just count with them, we count on them. Without numbers we wouldn’t know the time or date. We wouldn’t be able to buy things, count how many things we have, or talk about how many things we don’t have. So numbers had to be invented. The story of their origins is full of fascinating twists and turns, and it took people a long time to hit on the simple system we use today.
