Not the commutative property but the fact that absolute value is always positive so the absolute value of x is equal to the absolute value of negative x
-The commutative property could not have been used, because subtraction doesn’t apply to the commutative property -The answers are NOT the same. -If you subtract 4.2-3.4, it will be a positive number. But if you subtract 3.4-4.2, it would be negative.
