# Signed and unsigned numbers
|
|
|
|
## Summary
|
|
|
|
- To represent negative integers in binary we use signed numbers._Signed binary_
|
|
includes negative integers, _unsigned binary_ does not.
|
|
|
|
- There are different methods of implementing the encoding of signed numbers.
|
|
Two prominant approaches are **two's complement** and **signed magnitude
|
|
representation**.
