Why is zero important?
Zero's Big Journey
Why is zero important?
Imagine you're counting your birthday candles. One, two, three, four, five. Easy! But what if there are no candles yet? What number is that? For thousands of years, people didn't have a way to write "nothing." Then zero showed up, and everything changed.
Ancient Romans could count huge armies and build massive roads, but they had no symbol for zero. If a shelf was empty, they'd just leave a blank space in their records. That works fine until you try to do math. Is that blank space "nothing" or did someone forget to write something down?
