# Use index notation with numbers to establish the index laws with positive integral indices and the zero index (ACMNA182)

[/fusion_text][fusion_text]LO: To investigate index notation and use index laws to solve problems involving indices
Know:

• What indices are
• What index notation is
• The index laws
• What is a numerical expression

Understand:

• That index laws can be used to simplify numerical expressions.

Do:

• I can apply index laws to numerical expressions with integer indices.

### Numbers that have the same base number but different indices when divided, you just subtract the indices.
