## Fun Math Facts

- Algebra: One of the main branches of pure mathematics that studies operations and relations on numbers. Elementary algebra involves studying the rules of arithmetic on expressions involving variables. Advanced algebra involves studying these operations and relations on mathematical objects and constructions other than numbers.
- Algebraic expression: A mathematical expression in which variables or other symbols are used to represent numbers.
- Calculus: Calculus is a branch of mathematics that describes how systems and other mathematical constructions change across time and space.
- Coefficient: A numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g.,
*4*in*4x*). - Combination: A collection of things, in which the order does not matter.
- Complex numbers: A combination of a real and an imaginary number in the form a + bi, where a and b are real, and i is the "imaginary unit number".
- Constant: Sometimes a letter such as a, b or c stands for a fixed number.
- Exponent: The exponent of a number says how many times to use that number in a multiplication.
- Exponential function: A function whose value is a constant raised to the power of the argument, especially the function where the constant is
*e.* - Expression: Numbers, symbols and operators (such as + and ×) grouped together that show the value of something.
- Factor: A number or algebraic expression by which another is exactly divisible.
- Factorial: The product of an integer and all the integers below it; e.g., four factorial, denoted as 4! is equal to 24.
- Function: A function is a special relationship between values: Each of its input values gives back exactly one output value.
- Geometry: The branch of mathematics that deals primarily with shapes, lines, points, surfaces, and solids.
- Golden Ratio: The golden ratio, also known as the divine proportion, golden mean, or golden section, is a number often encountered when taking the ratios of distances in simple geometric figures such as the pentagon, pentagram, decagon and dodecahedron.
- Graph: A collection of points whose coordinates satisfy a given relation.
- Imaginary numbers: A number that when squared gives a negative result.
- Infinity: A number greater than any assignable quantity or countable number (symbol 8).
- Integer: A whole number; a number that is not a fraction.
- Irrational number: An Irrational Number is a real number that cannot be written as a simple fraction, any real number that cannot be expressed as a ratio of integers.
- Linear Equations: An equation between two variables that gives a straight line when plotted on a graph.
- Logarithmic function: A function (as
*y*= log_{a}*x*or*y*= ln*x*) that is the inverse of an exponential function (as*y*=*a*or^{x}*y*=*e*) so that the independent variable appears in a logarithm.^{x} - Matrices: A rectangular array of quantities or expressions in rows and columns that is treated as a single entity and manipulated according to particular rules.
- Permutation: The action of changing the arrangement, especially the linear order, of a set of items.
- Pi: The numerical value of the ratio of the circumference of a circle to its diameter (approximately 3.14159…).
- Polynomial: An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
- Prime numbers: A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.
- Pythagorean Theorem: In a right angled triangle the square of the long side is equal to the sum of the squares of the other two sides. It is stated in this formula: a
^{2}+ b^{2}= c^{2}. - Quadratic Equations: An equation where the highest exponent of the variable (usually "x") is a square (2). It is usually written ax
^{2 }+ bx + c = 0. - Rational number: Is any number that can be expressed as the quotient or fraction p/q of two integers, with the denominator q not equal to zero.
- Real number: Real numbers are numbers that can be found on the number line. This includes both the rational and irrational numbers.
- Probability & Statistics: Probability is a measure of the likeliness that an event will occur. Statistics is the study of the collection, organization, analysis, interpretation and presentation of data. It deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments.
- Term: A mathematical expression which may form a separate part of an equation, a series, or another expression.
- Trigonometry: Trigonometry is the study of the relationships between the angles of a triangle and the lengths of its sides. It is fundamental to all modern science.
- Variable: Letters or other symbols that represent unknown numbers or values.
- Zero: A number that has no quantity or value; the whole number between -1 and 1 with the symbol 0.
