Yes, 0 is a number.
If you draw a number line from -3 to +3, the number 0 is a valid position on that number line. You can't say that there is noting at the place holder 0. It is a valid number.
Also, you can solve equations that are set equal to 0,
x² + x – 3 = 0 is a perfectly valid equation...
0 is mathmatically defined..
Generally we use NULL or Ø, or may be some other symbol, to represent "nothing" or does not exist...

Hello. Both those who said 0 is a number and those who said 0 is not a number are both correct! The reason for this is that in mathematics 'number' is a very general term and mathematicians recognise various types of numbers.
First, the counting or natural numbers are considered to be 1,2 3, 4 etc. So here 0 is not a natural number.
Next we have the integer (numbers) which are all the natural numbers plus 0 and the negative numbers. So here 0 is a number.

Yes 0 is a number. How would the computers work without 0?

It's a number just like -3 is a number and â2 is a number.

Zero is a number whose meaning is "the absence of value."
It is a whole number. The concept of zero was discovered by the Mayans. It is also located on the real number line. What does this mean? It means that 0 is also a REAL NUMBER.

Yes, it is a member of the set of Reals, and the Integers. These sets are also closed groups under certain binary operations, like addition (subtraction). For example, if a and b are reals or integers, then a+b is also a member or the reals or integers. So, therefore, is a-a = 0.

0 is a representation of nothingness. It is a number insofaras it represents the lack of a value, which is itself an amount.
