Final answer:
A piece of data is logical if it conveys the idea of true or false, and this can be determined using the rules of logic. In mathematics, logical claims are determined to be true or false by using the rules of the mathematical system.
Step-by-step explanation:
A piece of data is called logical if it conveys the idea of true or false. This refers to information that is based on the rules of logic and can be determined to be true or false using those rules. In mathematics, logical claims can be determined to be true or false by using the rules of the mathematical system.
For example, in mathematics, the statement '2 + 2 = 4' is a logical claim because it conveys the idea of true, while the statement '2 + 2 = 5' is a logical claim because it conveys the idea of false.
