13. Slide 13 - What is a Definition ?

• Definitions are descriptions of objects or ideas and relationships between objects.
• For example, “Lines that are at right angles (90°) to each other”.
• Mathematical definition is a precise(準確),
• unambiguous (不含糊) description
• of an idea which everyone agrees.
• A definition does not contain unnecessary or redundant information about the object. In other words, it does not include properties that can be deduced from other parts of the definition.

• 定義 vs 特性

• A. Division by 0 is undefined because you cannot do it.
• B. Division by 0 is undefined because you cannot make 0 groups of something.
• C. Division by 0 is undefined in school curricula because college-level mathematics is needed to do this calculation.
• D. Division by 0 is undefined because there is no single answer that when multiplied by the divisor 0 gives the original number.
