The math of both of them is incorrect, Yang's because 100-10 and 90+9 do not equal 100, and greg because while 90+10 equals 100, 100-10 still does not.
The correct form for this math is 100x(90/100) = 90, and 90x(1+(10/100)) = 99, as they are two different equations, not an ongoing attempt to simplify the same equation.
