    I thought with “reversible” they meant that a number falling 50% and then rising 50% afterwards, it is the same number, which is not true.

    10 * 50% = 5

    5 * 150% = 7.5

      Yeah the correct term would be “commutative” as someone already pointed out. Meaning the order doesn’t matter when considering multiple percentages. E.g 50% of 73% of something is the same as 73% of 50% of that same thing
