Oof, I thought it was only constipated mathematicians that had to work it out with a pencil.

If you use too many parentheses you might have a lisp.

An IP address is a 32-bit number, usually expressed as four 8-bit numbers separated by dots. Converting 33333333 to hex we get 01FCA055; splitting that into pairs and converting back to decimal gives 1, 252, 160, 85.

Simple. We let them get away with it. Compare:

“Your PC is out of date” “Don’t be stupid, it’s only 2 years old and still works fine” with

“Your phone is out of date” “OK I’ll buy a new one”.

There needs to be a lot more of Answer A to Statement B.
