magnitude: the magnitude of a vector is its length.
major arc: an arc of measure greater than 180 degrees.
major axis: the line segment connecting the two vertices that are farthest apart in an
ellipse.
matrix: a table of numbers arranged in rows and columns.
maxima: the points on a curve where the value is greater than that of the surrounding
points.
mean: average, arithmetic mean.
median: the number in a group of numbers such that there are an equal number of
numbers in the set greater than the number as are less than the number.
midpoint: a point, M, on a line segment, AB, such that AM = MC.
minima: the points on a curve where the value is less than that of the surrounding points.
minor arc: an arc on a circle that is less than 180 degrees.
minor axis: the shortest distance across an ellipse through the center.
minute: the unit of measure of an angle that is 1/60 of a degree.
mode: the number that occurs most frequently in a set of data.
modulus: the absolute value of a complex number.
monomial: an algebraic expression that does not involve any additions or subtractions.
multiplicand: in the equation ab = c, a and b are multiplicands.
multiplication: the operation of repeated addition.
multiplicative identity: the number 1 is the multiplicative identity because 1 * a = a for all
a.
multiplicative inverse: the number, b, that when multiplied by a number, a, gives a result
of 1. Reciprocal. b = 1/a.
