Properties of Numbers: What Are Properties of Numbers?

The video tutorial introduces the concept of properties in both science and mathematics. It begins by explaining what properties are, using the example of pyrite to illustrate scientific properties like hardness and color. The tutorial then transitions to mathematical properties, describing them as rules or methods of operation. Finally, it focuses on the properties of addition, including the commutative, associative, and additive properties.

Which of the following is a property of the rock pyrite?

• It is transparent.

• It has a silver color.

• It is soft.

• It has a metallic shininess.

In science, what does a property refer to?

• A mathematical rule

• A characteristic of something

• A scientific experiment

• A type of rock

What is a property in mathematics?

• A rule or way an operation is done

• A type of scientific method

• A color of a mineral

• A characteristic of an object

Which property of addition states that the order of numbers does not change the sum?

• Distributive property

• Commutative property

• Additive property

• Associative property

What does the associative property of addition imply?

• The sum of two numbers is always even

• The sum of a number and zero is the number itself

• The order of numbers affects the sum

• Changing the grouping of numbers does not change the sum
