# 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**.
