The larger lines are ur whole numbers...the smaller lines in between each large line are in increments of 1/3. I did not draw the larger lines....they are where the whole numbers are...the lines I inserted are the 1/3 increments.
-6 2/3 -4 1/3

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0
does that make sense ?
