2. It all started in the middle of the 2 nd millennium BC. The people didn’t think we needed a zero they thought why do we need a number zero they refused to call it a zero. There are tow mane ways that the number zero can be used. first it can be used for an empty place value. Second it can be used for the number between the negative numbers and the normal numbers.
