## Subtopics

- Finite set [r]: The number of its elements is a natural number (0,1,2,3,...)
^{[e]} - Countable set [r]: A set with as many elements as there are natural numbers, or less.
^{[e]}

- Cardinality [r]: The size, i.e., the number of elements, of a (possibly infinite) set.
^{[e]}-->

- Integer [r]: The positive natural numbers (1, 2, 3, …), their negatives (−1, −2, −3, ...) and the number zero.
^{[e]} - Convolution (mathematics) [r]: A process which combines two functions on a set to produce another function on the set: the value of the product function depends on a range of values of the argument.
^{[e]} - Zermelo-Fraenkel axioms [r]: One of several possible formulations of axiomatic set theory.
^{[e]} - Galileo's paradox [r]: The observation that there are fewer perfect squares than natural numbers but also equally many.
