This trick just isn't adding up for me:

Take any whole number,
Subtract a shorter whole number from it,
Reverse what's left, then add 10 to it.

You will find, for any number you've picked, your answer will match it!

How can that be possible?

I'm not sure this is a regular answer but ... Take any whole number

integer - this is a whole number

Subtract a shorter whole number from it

int - this is a shorter word for a whole number, and subtracting leaves eger

Reverse what's left, then add 10 to it

rege + x (ten in Roman numerals)

You will find, for any number you've picked, your answer will match it!

regex - this can match it!
