I can explain how binary sequences are used to represent digital data. I can convert between binary and decimal.

## Count to 3β¦

We are used to counting in **decimal** because we have 10 fingers. We work with *place values* that go up in **powers of 10**:

1000 | 100 | 10 | 1 |
---|---|---|---|

Β | Β | Β | 3 |

## Count to 11β¦

Binary works the same way, but the *place values* go up in **powers of 2**:

8 | 4 | 2 | 1 |
---|---|---|---|

0 | 0 | 1 | 1 |
