What Are Real Numbers? Edit. Real numbers consist of zero ( 0 ), the positive and negative integers (-3, -1, 2, 4), and all the fractional and decimal values in between (0.4, 3.1415927, 1/2). Real numbers are divided into rational and irrational numbers.

Do we count from 0 or 1?

If you are counting things, start from one. That way, the number you are saying/thinking is the number of things you ‘ve counted. If you are counting intervals (miles, seconds, rotations) start from zero. That way, the number you are saying/thinking is the number of intervals you ‘ve completed.

Why do we count to 10?

Nature gave us ten fingers, and so it is natural for us to count in tens. Machines count bigger numbers in the same way we do: by counting how many times they run out of digits.
