Discover the key math terms that start with the letter ‘Z’ and enrich your mathematical vocabulary.

**Zero-**The number which represents no quantity or null value; it is the integer between positive and negative numbers.**Zeta function-**A complex function used in number theory, often related to the distribution of prime numbers, most notably the Riemann Zeta function.**Zenith-**The highest point or peak; often used in spherical geometry.**Zepto-**A prefix in the metric system denoting 10^-21.**Zigzag-**A line or course characterized by sharp turns in alternating directions; in mathematical terms, it represents a path or pattern.**Zillion-**An informal term used to describe an indefinitely large number.**Zone-**A region divided based on specific criteria; in mathematics, it can refer to areas in geometry.**Zeno’s paradox-**Philosophical problems that propose paradoxes in motion and time, significant in mathematical theory.**Z-**axis – One of the axes in a three-dimensional Cartesian coordinate system; it usually represents depth.**Zoo-**In graph theory, a structure also known as a “zoo” used to describe complicated and diverse collections of graphs.**Zorn’s lemma-**A proposition equivalent to the Axiom of Choice, used in set theory.**Zag-**A sharp change in direction; often paired with “zig” to describe a back and forth motion.**Z/2Z-**Notation representing the cyclic group of order 2, consisting of two elements.**Zener-**Named after the physicist Clarence Zener, refers to a specific voltage in electronics but also appears in mathematical equations.**Zener diode-**Though more an electronics term, itâ€™s used in mathematical formulas involving circuit design.**Zermelo-**Fraenkel set theory – The standard form of axiomatic set theory from which most of mathematics can be derived.
