### Operator, Expression & Statements

• MATLAB has been called an expression based language, it interprets and evaluates typed expressions. Expressions are constructed from a variety of things, such as numbers, variables, and operators.
• MATLAB has 14 fundamental data classes. The default numeric data type is double-precision.
• Several operations might be combined into a single expression, MATLAB has strict rules about which operations are performed first in such cases, these are called precedence rules, and you can find them in the following table.
• Precedence: 1   Operator: Parentheses (round brackets)
• Precedence: 2   Operator: Power, left to right
• Precedence: 3   Operator: Multiplication and division, left to right
• Precedence: 4   Operator: Addition and subtraction, left to right
• Expression: an expression is a formula consisting of variables, numbers, operators and function names.
• Statements: a statement usually has the form: variable = expression
