As any parent can see, middle school writing expectations are challenging. If your middle school student is at the below basic or basic level in writing, you need to take action.
In this case, has truth value F and from the second line of the tables above, we see the truth value of the compound statement is F. Had it been the case that p was false and q true, then again would be false and from the fourth row of the above table we see that. Similarly, directly translates as The wall is red and the lamp is not on' but it would be preferable to say The wall is red but the the lamp is off'. These and the truth values for the other connectives appear in the truth tables below. From these elementary truth tables, we can determine the truth value of more complicated statments. For example, what is the truth value of given that p and q are true?
The statement translates to The wall isn't red and the lamp is on'. Statements given symbolically have easy translations into English but it should be noted that there are several ways to write a statement in English.
Note that the connective or' in logic is used in the inclusive sense (not the exclusive sense as in English). Thus, the logical statement It is raining or the sun is shining ' means it is raining, or the sun is shining or it is raining and the sun is shining. If p and q are statements, then the truth value of the statement is T except when both p and q have truth value F. The truth value of is F except if both p and q are true. A statement that is always true is called logically true or a tautology. A statement that is always false is called logically false or a contradiction. Symbolically, we denote a tautology by 1 and a contradiction by 0. These and the truth values for the other connectives appear in the truth tables below. From these elementary truth tables, we can determine the truth value of more complicated statments. For example, what is the truth value of given that p and q are true? For example, the statement 2 3 5' has truth value T. Statements that involve one or more of the connectives and or not if then' and if and only if ' are compound statements (otherwise they are simple statements). For example, with the examples above, the statement directly translates as If the wall is red then the lamp is on'. It can also be stated as The wall is red only if the lamp is on' or The lamp is on if the wall is red'. Next: Logical equivalence and implication Up: NOTES ON SYMBOLIC LOGIC Previous: NOTES ON SYMBOLIC LOGIC. A statement is an assertion that can be determined to be true or false. The truth value of a statement is T if it is true and F if it is false. For example, It is not the case that 2 3 5' is the negation of the statement above. Of course, it is stated more simply as 2 3 5'. Other examples of compound statements are: If you finish your homework then you can watch T.V. If, for example, the statement p is known to be true, then in constructing the truth table of we will only have 2 rows. Truth tables involving n statements will have rows unless additional information about the truth values of some of these statements is known.

I came upon your advertisement about the job opening of a Marketing Manager in the Daily Newspaper dated 21st February, 2010. I am interested for this job position, and would like to apply for the same. Next: Logical equivalence and implication Up: NOTES ON SYMBOLIC LOGIC Previous: NOTES ON SYMBOLIC LOGIC. A statement is an assertion that can be determined to be true or false. The truth value of a statement is T if it is true and F if it is false.
For example, if p is a true statement then the truth value of is F. Similarly, if p has truth value F, then the statement has truth value T. These rules are summarized in the following truth table.
