Every decision you make in a computer program involves evaluating one or more expression(s).

Boolean expression.

Explanation:

Boolean algebra provides the operations and the rules for working with the set {0, 1}. In computer science, a Boolean expression is an expression in a programing language that produces a Boolean value when evaluated i.e. one of true or false.

Each Boolean expression represents a Boolean function. The values of this function are obtained by substituting 0 and 1 for the variables in the expression.

Are used mostly with while loops, and conditional statements and can be contrasted with arithmetic expressions which are expressions that evaluated to a number.

These expressions are made up of the three logical operators (AND, OR, NOT), the relational operator (> >= < = = <>) and functions that return true or false.
