Points to the right are positive, and points to the left are negative. A distance is chosen to be 1, then whole numbers are marked off: {1,2,3,...}, and also in the negative direction: {...,â3,â2,â1}. Any point on the line is a Real Number: 1  The numbers could be whole (like 7)  or rational (like 20/9)
