ABSTRACT
A vital aspect of computer programming is forming flawless expressions, as expressions are the heart of data processing. Arithmetic expressions process numeric data and, to a limited extent, character data. Relational expressions compare two values and return the result as TRUE or FALSE. Relational expressions help us in programming a decision-making capability into our programs. Then logical expressions help us to combine relational expressions so that our programs can make really complex decisions. Then there are arithmetic operators that we can use to formulate arithmetic expressions; relational operators that are used in formulating relational expressions; and logical operators that help us in formulating logical expressions. All of these operators are enumerated and explained in detail so that the reader is equipped to formulate efficient expressions that return accurate results. The best practices in formulating these expressions are enumerated and explained in detail so that the reader is equipped with all the tools necessary to formulate effective arithmetical, relational, and logical expressions.
