The ancient Egyptians had a conception of zero, and used a herioglypical symbol for zero. China had a counting rod system, with an empty space being a zero and Mathematical Treatise in Nine Sections had a round symbol being used for zero. Other authors were familiar with the concept of negative numbers.
These are alll before Indian "invention" (probably be discovery) of zero.
