The function of the variables is not only store texts and numbers, they can be modified at any time by the programmer, through operators, commands and new assignments. In Logic Basic we can work with four types of operators: Arithmetic operators, increment and decrement operators, comparison and logical.
Arithmetic operators:
+

*
/
%
^
Sum
Difference
Multiplication
Division
Rest of division
Exponentiation
Increment and decrement operators:
++

+=
=
Adds 1 to himself
Decreases 1 of himself
Adds a number to it
Decreases a number of it
Comparison operators:
=
<
>
<=
>=
<>
Equal
Less than
Greater than
Less than or equal
Greater than or equal
Different
Logical operators:
And
Or
Logical conjunction
Logical disjunction
Union operator:
&
Join strings or variables
The = operator is a comparison operator only when it's inside a comparison expression, in other situations it's an assignment operator.
