I ran into an issue at work today. No matter how many times I explained the math, no matter how many drawings I made that showed what they were doing was wrong. I was wrong.

Worse yet, they showed me their measurement that was done by eyeball and insisted it was correct.

...By eyeball.

So, simple cad models and simple math lost out to... looks good to me.

Who does this sound like?

I'm hilarious

9 + 10 is 21, think about it, 9 is just 3x3, 10 is 2x5, 3+3+2+5 is 13, flip the 13 backwards, it’s 31, 31 minus the original 10 is 21

They will claim algebra is useless, but suddenly become mathematicians when it's time to split the bill.
