## Binary Addition Example

Consider the following example:

1010 | |

+ | 0111 |

= |

Is calculated from the right as 0 + 1 is 1. 1 + 1 is 0 carry 1. 0 + 1 + 1 is 0 carry 1. 1 + 0 + 1 is 0 carry 1. The carry is then placed into the next column giving

1010 | |

+ | 0111 |

= | 10001 |

It is important to check your answer. We can do this by converting to denary and performing the addition. 1010 is 10. 0111 is 7. 10 + 7 is 17 which is 10001.
