BASIC Arithmetic Operators

They are expressed in terms of a hierarchy of operators in which operations of high priority are performed first.

Examples:

Operator Symbol Operation
^ Exponentiation
* Multiplication
/ Division
Subtraction

BASIC Arithmetic Expressions

These arithmetic Expressions are not formed according to the same rules of Algebra and Mathematics. The following symbols are used to denote arithmetic operations.

Operators Meaning Basic Expression Math Equivalent
+ Addition $$A= A + B$$ $$A = A + B$$
Subtraction $$Sum = Sum -10$$ $$Sum = Sum -10$$
* Multiplication $$J = J * 4$$ $$J = 4J$$
/ Division $$Pi = \frac{22}{7}$$ $$Pi = \frac{22}{7}$$
^ Exponentiation $$J = J + 2^2$$ $$J = J + 2^2$$

Basic Relational Operators

Operator Relation Tested Expression
= Equality $$X = Y$$
< > Inequality $$X < > Y$$
< Less than $$X < Y$$
> Greater than $$X > Y$$
<= Less than or equal to $$X <= Y$$
>= greater than or equal to $$X >= Y$$
