The integers
[ilmath]\mathbb{Z} [/ilmath]

Definition

Properties

The integers, coupled with the operations of addition[Note 1] and multiplication[Note 2] forms a Q-ring, [ilmath](\mathbb{Z},+,\times)[/ilmath]

Notes

  1. In the obvious way, [ilmath]+(a,b)\eq a+b[/ilmath]
  2. Again, obvious: [ilmath]\times(a,b)\eq a\cdot b[/ilmath]
