For the following sentences, decide which ones are statements. If it is a statement, then write its negation. Write S or NS for statement or not a statement, respectively.
(a) Thomas Jefferson was the 23rd president.
(b) Sit down and be quiet.
(c) If wages continue to rise, then prices will also rise.

Oh my gosh, guys.
(a) S;
Thomas Jefferson was not the 23rd president.
(b) NS
(even if you give the opposite command, it will still be a command and not a statement)
(c) S; symbolic form: p->q; negations:
[p & ~q]: Wages continue to rise and prices do not rise. (or, if expressed in more "natural" English, ... yet prices do not rise too / but prices do not rise too).
Or [~p (arrow pointing downwards, sign of rejection) q]: neither wages do not continue to rise, nor do prices rise.
Or [~(~pvq)]: it is not the case that wages do not continue to rise or prices do rise.
supplement: a statement is an expression that can be characterized as true or false. This is the case for (a) and (c), but is clearly not the case for (b). This is why (b) is the only NS up there. "Somebody gave me a thumbs down for no reason" is another example of a (true) statement.

(a) NS
(b) NS
(c) NS
All of the above are not statements because such is a single declarative sentence which all of the above does not posess.
