    I’ve always wondered how to disambiguate multiplication and addition of percentages. I guess that’s what percentage points are for?

      The annoying part is that there is no well-known notation for showing percentage points, so people use % for both percentages and percentage points.

        I like how some games use “increases by +10%” as percentage points and “increases by 10%” as percentage.

        Or how oath of exile does it, with “(base + base * increases by y%) * z% more”

        So with a base of 5%, chance increased by 20%, and chance increased by 30%, with a 40% more chance, you’d get:

        (5% + 5% x (20% + 30%)) x (1+40%) = 7.5% x 1.4 = 10.5%

        In deep rock galactic survival, the color of the number is different for percentage and percentage points

      Exactly. Unfortunately, they aren’t used widely and consistently enough. Even in the press. So you frequently have to second guess what you’re reading.

      10% of your people vote for a party.

      The votes increase by 10% => now 11%

      The votes increase by 200% => now 30%

      The votes increased by 50 percent points => now 60%
