Answer 2

Explanation:

The ancient Greeks and Egyptians had no zero. They used completely different symbols for 9, 90, 900 and so on. This system has a couple of big disadvantages.

First, it only has symbols for numbers people have already thought of. If you want to talk about, say, 900 billion, you may have to invent a symbol for it.

Symbols

The old Greek and Egyptian systems also make arithmetic hard. Without zero, multiplying 3 times 90 is a whole different problem from multiplying 3 times 9.

Some of the first known zero symbols appear in Babylonian clay tablets of between 400 and 300 B.C.; there the zero was used to clarify the symbols for large numbers.

mathematician Leonardo Fibonacci.

Thanks to zero, we can punch any number into our calculators using just ten keys. And if we want to imagine some gigantic number, we can do it easily, just by adding more zeros.

Zero is one of humanity's greatest inventions; a symbol that stands for nothing in a very definite way.
