Quadratic:An algebraic expression where the pronumeral??s highest power is 2 and there are no negative or fractional powers.

Trinomial:A trinomial is a polynomial with three terms. A polynomial with three terms is called a trinomial.

Placement:the act or process of finding work or a job for a person.

Denominator:What is it? The bottom part of a fraction.

Algebraic equation:an equation of the form f (x) = 0 where f is an polynomial.

Fraction:A fraction is a number between zero and 1 and is expressed as one number over another number.

Factorising:Finding what to multiply to get an expression. (Called Factoring in US English.) Example: 2y+6 = 2(y+3), so the factors of 2y+6 are 2 and (y+3)

Scale model:A model or drawing based on a ratio of the dimensions for the model and the actual object it represents (e.g., a map).

Equation:A mathematical sentence that uses an equals sign to show that two quantities are equal.

Algebra:The substitution of symbols and letters for numerical variables and constants. These symbols can be manipulated in the same way as numbers and form the basis for most mathematical calculations.

Line:A line is a set of points that form an infinitely long straight path that extends in both directions. The equation y=mx+b or ax+by+c=0 graph a line (these are linear equations).

Each:every one considered separately or one by one.

Math:Mathematics is the study of quantity, structure, space and change. It developed, through the use of abstraction and logical reasoning, from counting, calculation, measurement, and the study of the shapes and motions of physical objects.

Graphing calculator:A larger screen calculator that's capable of showing/drawing graphs and functions.

Trinomial:An algebraic expression consisting of 3 terms.

Square root:x is the number that,when multiplied by itself gives the number, x,

Problem solving:Solving a problem using mathematics.

Algebra:Algebra is the area of mathematics where letters (like x or y) or other symbols are used to represent unknown numbers.

Calculator:A machine for performing arithemtical calculations.

Algebra:Algebra is the branch of mathematics that uses letters, symbols, and/or characters to represent numbers and express mathematical relationships. Those symbols are called variables.

Linear system:A set of two equations in the form Ax + By = C where A, B and C are constants. This set of two equations in two variables can be solved by graphing substitution or elimination.

Algebra:A branch of mathematics that substitutes letters for numbers.

Simplification:algorithms Line simplification algorithms have been developed over the years for the purpose of 'weeding out' redundant or unnecessary coordinate information from line features, whilst retaining the perceptual characteristics of the line. They generally work via the application of some geometric criterion to a line's coordinate pairs (such as distance between points or displacement from a centre-line). (for more on line simplification go to the Line Generalisation module)

Multiply:To add the same number to itself several times. It is an operation of repeated addition. For example, 4 + 4 + 4 = 3??4 = 12, in which "3??" means "repeat the addition 3 times.

Expression:numbers contained with one or more operations.

Algebra:arithmetic operations using letters and/or symbols in place of numbers.

Calculator:a tool used to figure out the answer to a number problem

Problem:A question that needs a solution.

Calculator:Usually hand-held, pocket-sized electronic device for performing numerical calculations, organizing data, graphing functions, and/or performing symbolic manipulations. Simpler calculators can perform basic operations including addition, subtraction, multiplication, and division. More specialized calculators perform operations with squares, roots, certain trigonometric and statistical functions. They store and sort data lists or programs, and create an assortment of graphs.

Combination:a sequence of letter or numbers chosen in setting a lock.

Exponent:A number that indicates how many times a number or expression is to be multiplied by itself. Example: In the expression 5^3, the exponent is 3.

Math:The grammar of size (amount), shape, and/or order. (according to Lancelot Hogben in Mathematics for the Million) The study and description of patterns A way to describe measurements of reality in symbols There are many other ways to define, describe, and use math. No one can name them all, but it is fun and deeply satisfying to investigate them.

Trigonometry:1. n. study of triangles, the measurements of their parts and of angle functions and relations. EX. Originally trigonometry meant triangle measure.

Algebra:A branch of mathematics that substitutes letters for numbers.

Simple interest:Interest calculated using the formula I = prt, where I is interest paid, p is principle, r is the interest rate charged, and t is the time period.

Differential:It has something to do with the transmission of your car, but it's way too complicated for us to understand. Oh, yeah, a differential is also a small change in a variable. For instance, dy is a small change in the value of y. Although dy often occurs as part of the symbol for the derivative and as part of the symbol for the integral, and although in those other guises, dy plays a role very similar to the one intended when we call it a differential, it is best to just think of the differential dy

Algebra:a language that helps translate real-life situations into mathematical form so that we can analyze change and answer the question "What if?

Factorization:a way to write a number as the product of prime factors, for example: 2 x 2 x 3 x 5 = 60

Graphing calculator:A larger screen calculator that's capable of showing/drawing graphs and functions.

Completing the square:Process used to solve quadratic equations by forcing them to contain binomial perfect squares.

Radical expression:an expression especially an irrational number or quantity involving a radical sign.

Trigonometry:The study of the relationship between angles and sides in a triangle.

Factoring:Finding what to multiply to get an expression. (Called Factorizing in British English.) Example: 2y+6 = 2(y+3), so the factors of 2y+6 are 2 and (y+3)

Second order differential equation:An ordinary differential equation of order 2. That is, a differential equation in which the highest derivative is a second derivative.

Calculator:A calculator is a machine that solves math problems.

Multiply:To compute a product; to perform a multiplication.
