The document discusses the semantics and logic of Boolean formulas. It defines the values true and false as 1 and 0, respectively. It then provides truth tables showing the values of various logical operators including "not", "and", "or", and "xor" when applied to combinations of true and false inputs.

4. can take the values ​true and false.
The semantics is the set of rules
that give meaning to a formula.
The value of a formula is given by
traders as truth tables.
From now, we will assign the
false value 0, and the true 1.

18. RELATIONSHIPS

21. to create a table in MySQL, we must first declare it
with the command: CREATE TABLE
followed by the name we want to have our table,
after we open parenthesis and declare variables
and the variable type that are close parenthesis &
finally we add a semicolon.

22. Then with the command: INSERT INTO VALUES
assign a value to each variable and so we
fill our table. The variables that change
box are separated by commas and
quotation marks.
Finally, close the parentheses and
semicolons added.

23. To display the table, use the command:
SELECT * FROM followed by the name of
the table and ended with a semicolon.
After that, our table below shows the
values ​that we add, already full.

28. First, declare the table like this:
<TABLE ALIGN="center" BGCOLOR=CC0066 BORDER="10" CELLPADDING="10"
CELLSPACING="10">
In ALIGN we put the type of alignment you want, in
this case is centered and is enclosed in quotes in
English: "center"
BGCOLOR is that after the "same" color code say
that we want the background, or his name in
capital letters.
then declare the size BORDER is wide
