Can you please explain this

"The only way this absolute value difference would be less than 1/2 is if it is zero"
Dear gps5441,

I'm happy to respond. :-)

I'm going to ask you to think about the context of that statement:
R & B are integers, because they are counts. The difference (R - B) could be any integer, positive or negative or zero. The absolute value |R - B| could be any positive integer or zero. The only way this absolute value difference would be less than 1/2 is if it is zero.

The final statement is a consequence of all the previous statements. Which statements in this argument do you not understand?

Mike :-)
