Basic Properties
- Closure -> Product and sum are integers
- Commutativity -> Result of addition or multiplication is the same regardless of order of the operands
- Associativity -> Result of multiple operations is the same regardless of order of the operations
- Distributivity -> Multiplication is distributive over addition, but not the opposite
- Trichotomy -> Two integers are exclusively either equal to, less than or more than each other
The
comes from the German word for numbers “zahlen”
