Pascal Operators

Useful Theory and Math - Module 2

3. Arithmetic Operators

We're going to need these in order to do some math on Pascal, and trust me you'll need that alot.

Addition +
Subtraction -
Multiplication *
Division /

You can also prioritize certain parts of an operations like this.

Example:

10 + 3 * 6 =

10 + 18 =

18

If you put that in pascal it would go about completing the operation like that. If you use brackets you can prioritize certain parts of the operation.

Example:

(10+3)*6=

13*6=

78

4. Relational and equality operators

Equality =
Less than <
Greater than >
Less than or equal to <=
greater than of equal to >=

5. Logical Operators

These are operators which perform a boolean operation, they will evaluate to either true or false.

NOT
AND
OR

NOT example:

Consider the variable P

P = True;
Not P = False;

 P = False;
Not P = True;

AND example:

Consider variables P and Q

P = True;

Q = True;

P and Q = True;

P = True;

Q = False;

P and Q = False;

P = False;

Q = True;

P and Q = False;

P = False;

Q = False;

P and Q = False;

OR example:

P = True;

Q = True;

P or Q = True;

P = True;

Q = False;

P or Q = True;

P = False;

Q = True;

P or Q = True;

P = False;

Q = False;

P or Q = False;
