    I have 100 dollars. I lose 10% of it. I now have 90 dollars. Now I increase my 90 dollars by 10%. Is it your assertion that 10% of 90 is 10?

      No. Because increasing 90 by 10% is:

      90 • 1.1 = 99

      Percentage is relative to current value, not previous calculations. 10% of 90 is 9.
