Show the conhecture is false by finding a counterexample...

1. The differnece of the absolute value of two numbers is positive meaning
/a/ - /b/ > 0

I do not get that.... =/

HELP.

If absolute value of a is greater than the absolute value of b, then the difference has to be positive, greater than zero.

example: a= -7
b=4

abs a= 7
abs b= 4
abs a - abs b=3, or it is greater than zero.
