| Read time | What to take away |
| 1 second | Indices are rules for handling repeated multiplication. |
| 10 seconds | For the same base, multiply by adding powers, divide by subtracting powers, and raise a power to a power by multiplying powers. |
| 100 seconds | Example: in standard form, multiply the front numbers and combine the powers of ten, then adjust so the front number is at least 1 and less than 10. |
