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. |
