# Field
|
|
|
|
- Set on which addition and multiplication defined
|
|
- Behave same as on rational and real numbers
|
|
- Subtraction, division implied
|
|
- Examples
|
|
- Rational numbers
|
|
- Real numbers
|
|
- Complex numbers
|
|
- Any field can be used as scalars for a vector space
|
|
- A commutative ring where 0 =/= 1 and all nonzero elements are invertible
|
|
|
|
## Vector Space
|
|
- Set of vectors
|
|
- Can be added together and multiplied by scalar
|
|
- Can be scaled by complex numbers
|
|
- Part of definitions
|
|
- Must satisfy vector axioms |
