Me as a British:

tip = don't live in a country where tipping is the regular thing to do

Easiest way to calculate this is just multiply your bill with 0 and you’re good to go

fun fact: switching x and y's spots is because "x% of y" is basically just multiplication. percentage is just a decimal multiplied by 100, so instead of it being 1/1 it's 100/100. And the "of" is just saying multiplied by, "x% of y" is just "x*y" with x being a decimal, 1 for 100% and 0 being 0%.

The first tip is only helpful on numbers that are easy to use as percentages (10, 25, 50, 75, 100, etc). Otherwise if you try to, for example, find 8% of 8, it wouldn't make it any easier. This is the same for almost any number.

The first time solving by Y and X have been atleast kind of useful to us normal humans.

That’s why I always tip 20%… just multiply the bill by 2 and move the decimal right on spot

when you realize that, useful maths are just simple, yet they still teach us breathtaking mathematics.
