well, look at it here and there
x always left of y on number line
x=-2 y=-1 -> x-y = -1 and |x-y|=1
x= 8 y= 10 -> x-y = -2 and |x-y|=2
in fact if x < y then x-y is ALWAYS - and |x-y| = y-x
so I conclude
y-x
Write each of the following expressions without using absolute value. |x−y|, if x<y I reall don't get this please help
