Natural numbers are naturally used for counting apples (and other things) so they are sometimes called counting numbers. Even some animals other than humans can count and add, so they must be natural. Minus two apples isn't very natural so negative numbers are not included.
Natural numbers ( N {\displaystyle \mathbb {N} } ): The counting numbers {1, 2, 3, â¦}, are called natural numbers. Some authors include 0, so that the natural numbers are {0, 1, 2, 3, â¦}. Whole numbers: The numbers {0, 1, 2, 3, â¦}. Integers ( Z {\displaystyle \mathbb {Z} } ): Positive and negative counting numbers, as well as zero:{â¦, -2, -1, 0, 1, 2,â¦}. Rational numbers ( Q {\displaystyle \mathbb {Q} } ): Numbers that can be expressed as a ratio of an integer to a non-zero integer. All integers are rational, but the converse is not true.
