Small notice
In English school math they treat these words "The difference between x and y" in two ways.
One way is simply x-y.
The other way is |x-y|.
Often they can not to get an agreement on how to treat it.
But it is "as is", and I can not influence it.
In real MATH, however, there is no such a duality.
In real MATH, "the difference between x and y" is x-y.
