! "One Thousand Five Hundred" =~ "T[^ ]" |
0 | Because it applies to the string, which is non-null, which it turns to "0", and then looks for the pattern in the "0", and doesn't find it |
!( "One Thousand Five Hundred" : "T[^ ]+" ) |
1 | Because the string doesn't start with a word starting with T, so the match evals to 0, and the ! operator inverts it to 1 |
2 + 8 / 2 |
6 | Because of operator precedence; the division is done first, then the addition |

Of course, all of the above examples use constants, but would work the same if any of the numeric or string constants were replaced with a variable reference, e.g. ${CALLERID(num)}.
