A warm welcome to you mathematician, u remind of a mathematician joke from Reader's digest( https://www.rd.com) which I quote below

''A mathematician wanders back home at 3 a.m. and proceeds to get an earful from his wife.

“You’re late!” she yells. “You said you’d be home by 11:45!”

“Actually,” the mathematician replies coolly, “I said I’d be home by a quarter of 12.”
