Mass · M

A measure of the inertia of a mass of matter, one of four fundamental properties of matter. SI unit of mass: kilogram.

Maximum · M

The greatest value of a set or other mathematical structure, especially the global maximum or a local maximum of a function.

Mean · M

Any function of multiple variables that satisfies certain properties and yields a number representative of its arguments; or, the number so yielded; a measure of central tendency.

Median (geometry) · M

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length. The concept of a median extends to tetrahedra.

Meter · M

The base unit of length in the metric system, equal to 100 centimeters.

Midpoint · M

A point which divides a line segment into two lines of equal length.

Minimum · M

The smallest member of a batch or sample or the lower bound of a probability distribution.

Minor arc · M

A minor arc may refer to: An arc that is smaller than a semicircle A term that arises in connection with the Hardy–Littlewood circle method

Minus · M

The sign −, indicating subtraction or a negative number.

Mixed number · M

A number consisting of a whole number and a fraction, such as 11½.

Mode · M

A state of a system that is represented by an eigenfunction of that system.

Modulus · M

The absolute value of a complex number.

Multiple · M

A whole number that is obtained by multiplying a specific whole number by another whole number.

Multiplication · M

The process of computing the sum of an addition with one and the same number a specified number of times (i.e. 4 times 5 = [0 +] 5 + 5 + 5 + 5 = 20) or any other analogous binary operation that combines other mathematical objects.
