Operators and Expressions

Operators are symbols that instruct the interpreter to perform mathematical or logical manipulations, while expressions are combinations of values, variables, and operators resulting in a value. The chapter covers various types of operators including arithmetic, assignment, comparison, and logical operators, highlighting their roles in performing operations and writing expressions. Understanding these operators is essential for predicting the output of expressions and achieving desired programming outcomes.
