Definition

**Good Job** **4pts** __Combinatorics__ **Definitions should be the title.**

Combinatorics (term to be defined) is a The science (general class word) that studies the numbers of different combinations, which are groupings of numbers. Combinatorics is often part of the study of probability and statistics (characteristics). **Good** Cube A cube (term to be defined)  is a prism (general class word) with six square faces (characteristics)

Degrees **??**

A circle is measured in units (general class word) called degrees (term to be defined). The entire circle is 360 degrees, half a circle is 180 degrees, and one quarter of a circle is 90 degrees. The "L" shaped 90 degree circle forms what is called a right angle. When examining circular objects, such as spinners, the size of each segment in the circle can be described in degrees (characteristics)

Denominator In a rational number (general class word), the number below the fraction bar (term to be defined) that indicates how many parts the whole is divided into (characteristics). See also numerator

Fraction A fraction (term to be defined)  is a rational number (general class word) of the form a/b where a is called the numerator and b is called the denominator (characteristics).

Function

A function (term to be defined)  f of a variable x is a rule (general class word) that assigns to each number x in the function's domain a single number f(x) (characteristics). The word "single" in this definition is very important.

Graph A graph (term to be defined)  is a visual representation (general class word) of data that displays the relationship among variables, usually cast along x and y axes (characteristics).

Histogram

A histogram (term to be defined)  is a bar graph (general class word) such that the area over each class interval is proportional to the relative frequency of data within this interval (characteristics).

Line

A line (term to be defined)  is a continuous extent of length (general class word) containing two or more points (characteristics).

Multiplication Multiplication (term to be defined)  is a operation (general class word) by which the product of two quantities is calculated. To multiply a number b by c is to add b to itself c times (characteristics). Definition **S** with my own words

Square It is a geometric figure with four equal sides and four right angles. **Good** Pythagorean Theorem It is a formula used to calculate the hypotenuse measure or any of its other sides of a right triangle. **Good** Negative Numbers **They** Are numbers that are represented by the set of integers, and all negative numbers are less than zero. **Good** Euclidean algorithm It is one way to find the greatest common divisor and least common multiple through a series of simple divisions. Decimal Numbers **Capitalize** __a__ decimal number is a way of writing a fraction which is not an integer, these numbers are represented by the set of rational numbers. **Good**
