  • A set or the set of? Usually, in maths \mathbb Ndenotes the set of natural numbers. You also can use \mathbf N, but then, you must use the same notation for all sets of numbers. – Bernard Mar 12 '14 at 1:00

    your question appears to be about notation rather than tex so may be off topic, but I'd normally denote the set of integers by \mathbb{Z} (with N being natural numbers rather than integers. – David Carlisle Mar 12 '14 at 1:01

You could use \mathbb{Z} to represent the Set of Integers!

    It's useful here to mention that \mathbb is defined in the package amfonts. – barbara beeton Jan 24 at 20:40
  • package amsfonts and not amfonts – AntoineP Mar 10 at 10:49
