Let's look at how we do things with conventional symbolism. *Do note that the symbolization used here is perhaps the most common but it is definitely not the only system in use.**.*

For the connectives (what we called signals before) we have one less than in PLN.

negation: ~P (PN) *read as curl P*

conjunction: P & Q (PQA) * P ampersand Q*

disjunction: P v Q (PQO) *P wedge Q*

implication: P -> Q (PQC) *P arrow Q*

biconditional (mutual implication): P <-> Q (PQB) *P double arrow Q**For mutual exclusion (exclusive disjunction, or the sense of 'or' when only one choice is possible), we need to use a more roundabout expression: ~(P <-> Q) or (P v Q) & ~(P & Q).*

With postfix notation grouping was handled automatically by the placement of the signals. For infix notation we have new punctuation with parentheses:

PQRAO would become P v (Q & R) while PQARO is (P & Q) v R.

In more complex expressions we may need to nest the parentheses. For instance, PQRAON would become ~(P v (Q & R)).

Because there are no longer letters for signals, we do not need to restrict the letters used for variables, and we do not need to set up a code as we do in PLN. Normally, we will symbolize by using a letter that goes with the English words, as in the example below.

The test is not easy but the students are ready. ~T & S or maybe ~E & R

While I am not sure I can answer the question thoroughly, I do sense that all of the answers thus far seem to dance around the target. A good starting point might be to establish a common definition of non-traditional security issues or threats.

- Enter a number or a decimal number or scientific notation and the calculator converts to scientific notation, e notation and engineering notation formats. To enter a number in scientific notation use a carat ^ to indicate the powers of 10. You can also enter numbers in e notation.
