Modulus: a number whereby two provided numbers can divide by integer division, and create the same remainder, for instance, 38 ÷ 12 = 3 remainder 2, as well as 26 ÷ 12 = 2 rest 2, for that reason 38, as well as 26, are conforming modulo 12, or (38 ≡ 26) mod 12.
Monomial: an algebraic expression consisting of a solitary term (although that term could be a backer), e.g. y = 7x, y = 2×3.
Math dictionary: Letter “N”
Natural numbers: the set of positive integers (normal entire counting numbers), sometimes consisting of absolutely no.
Negative numbers: any integer, supply or a genuine number less than 0, e.g. -743, -1.4, -√ 5 (yet not √ -1, which is an imaginary or intricate number).
Non-commutative algebra: It is an algebra in which an x b does not always equivalent to b x a, such as that used quaternions.
Non-Euclidean geometry: It is based on a rounded aeroplane, whether elliptic (round) or hyperbolic (saddle-shaped). There are no angles of a triangle and parallel lines not sum to 180 °.
Normal (Gaussian) distribution: a constant probability distribution in probability theory and stats that describes the information which clusters around the mean in a bent “normal curve”, highest possible in the middle and swiftly lessening per side.
Number line: a line on which all factors correspond to genuine numbers (a manageable number line may only note integers. However theoretically can show all real numbers to +/- infinity on a number line).
Number concept: the branch of pure math concerned with numbers’ residential or commercial properties as a whole, and integers in particular.
Ordinal numbers: an expansion of the natural numbers (different from integers and preliminary numbers). It defines the order sort of sets, i.e. the order of elements within a group or series.
Math dictionary: Letter “P”
Parabola: a sort of conic area curve, any point of which is equally far-off from a dealt with focus factor and a set straight line
Paradox: a statement that appears to oppose itself, suggesting a remedy which is impossible
Partial differential equation: a connection including an unidentified function with several independent variables and also its partial by-products concerning those variables
Perfect number: a number that is the amount of its divisors (excluding the number itself), e.g. 28 = 1 + 2 + 4 + 7 + 14
Periodic function: a feature that duplicates its values in normal intervals or periods, such as the trigonometric functions of sine, cosine, tangent, and so on
Permutation: a specific purchasing of a collection of objects, e.g. provided the set, there are six permutations: 1, 2, 3, 2, 1, 3, 3, 1, 2, and 3, 2, 1
Pi (π): the proportion of a circle’s circumference to its diameter, an unreasonable (as well as transcendental) number around equal to 3.141593.
Platonic solids: the five regular convex polyhedra (in proportion to 3-dimensional forms). The tetrahedron (composed of 4 regular triangles). The octahedron (composed of 8 triangular) and the icosahedron (comprised of 20 triangular). The dice (consist of 6 squares) and also the dodecahedron (consisting of 12 pentagons).

Place value: positional notation for numbers, allowing the use of the very same signs for different orders of magnitude, e.g. the “one’s place”, “ten’s location”, “hundred’s location”, etc.
Polar coordinates: a 2-D coordinate system in which its range r identifies each point on a plane from a fixed factor. And its angle θ (theta) from set instructions.
Polynomial: An algebraic equation or expression with more than one term, built from variables. And also constants utilizing only the procedures of enhancement, reduction, multiplication. As well as non-negative whole-number backers, e.g. 5×2– 4x + 4y + 7.

Quaternions: a number system that prolongs complex numbers to four dimensions. (So that a genuine number explains an item. As well as three complex numbers, all mutually vertical to every other). It can use it to stand for a three-dimensional rotation by just an angle and a vector.
Quintic equation: a polynomial degree of 5 of the form ax5 + bx4 + cx3 + dx2 + ex lover + f = 0. Not understandable by factorization right into radicals for all reasonable numbers.
Math dictionary: Letter “R”
Reasonable numbers: numbers that can be shared as a portion (or ratio). A ⁄ B of two integers (the integers are for that reason a subset of the rationals). Additionally a decimal which ends after a finite variety of digits or starts to repeat a sequence
Real numbers: all numbers (including natural numbers, integers, decimals, sensible numbers as well as illogical numbers). It does not entail fictional numbers (multiples of the fictional device i, or the square root of -1). May be thought of as all factors on a considerably long number line
