This reminds me of how well I can do algebra and calculus but need to whip out the calculator for the tip.
Tips are easy. You move the decimal point (10%) and double (20%). Or find 10%, half of 10% is 5% and add that 5% to whatever 10% was for a 15% tip. And fudge the numbers to make the math easier when it makes sense to, it’s a tip not a math test.
Easy for you to say! You don’t have scrambled eggs for brains. 😜
You’re going to far. 0% of any sum is 0
u/lukmly013 💾 (lemmy.sdf.org)What are you guys talking about? Tip is just rounding up to banknotes-only. €37.25? You pay 2x€20.
This is the way I do it. Often I just divide by ten and multiply by two, but I’m a generous tipper, and it’s one less head math step.
The funny thing is that this basically how common core math works: get to the answer by doing as much easy math as possible.
Another method: tax is 8%, so double that as a baseline and adjust from there.
