Lesson: 12: Whole Numbers
Topic: Binary and Base Five Numbers
Domain: Number

The base of a number system is how many you count before carrying. It decides the place values and the digits, and base ten is a habit rather than a law.

Study Tip

Convert by dividing repeatedly and reading the remainders upwards, never downwards. Then convert back with place values, because that check costs ten seconds and catches almost everything.
