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

      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%

      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%

      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.
