1 and 40 share something - let's call it X - which isn't shared by any other number in the entire numbering system. The X in the first is a mirror of the X in the second.
What is X?

All I could think of was some cheesy type of bit reversal if both numbers were hex base. But that's sooo not the intended answer.

It's one of those questions the average 7-year-old could answer, they haven't learned to think inside the box yet. No formulas required, I dreamed it up during an insomniac episode - and the damn thing woke me up!

The letters in their English names are in (reverse) alphabetical order.
I'm not sure the average seven-year-old would have found that answer.

Most 7-year-olds can figure out the old HIJKLMNO = WATER one, so I figured this one would be a piece of cake! ðŸ™‚

twenty and thirty are probably irregular just like twelve and thirteen is, but fourteen isnt

in german the puzzle works with 1 and 8 being the only numbers having letters in alphabetical order (E-I-N-S and A-C-H-T).

In the "times 10" tables
one - ten
two - twenty
three - thirty
four - forty
five - fifty
SIX - SIXTY
SEVEN - SEVENTY
eight - eighty
NINE - NINETY

there are twice as many "irregular" as "regular". Maybe it's the "regular" group which are irregular. ðŸ™‚

Twoty and threety don't exactly roll off the tongue. I can understand why they were changed. That's also why I left them out of my examples. But consistency should be maintained if possible.
