If my kids are weebs with poor eyesight, it can serve as their nickname, I guess. Otherwise, they can pretend it’s just an uncommon surname.

Yeah, even if’d think of it as a flat 20% tax on top (as an estimate), it’d still be a bit too much for my mental maths.

Let’s see… If I’ve got 30 USD running total, then I estimate a 20% total tax… No, let’s do it as 25%. That’d be around 37.50 USD with the tax estimate. Doing it as 20%, it should be around 36 USD.

Doing the calculation with 17.5% via a calculator, it is 35.25USD. Doing it with 20% seems to be close enough, 25% a bit too much. But that depends on what’s the total tax percentage–or if it even works that way. It’s something I’m too unamerican to understand.

And that’s probably one of the few remaining uses of mental arithmetic I have nowadays. I also got to practice rounding up numbers for estimating whether or not I’ve got enough money for groceries. It’s easier to keep up with a running total in my head if they’re nice (rounded-up) numbers instead of being surprised at the total cost at the end.
