Equation an expression or a proposition, often algebraic, asserting the equality of two quantities.
Expression Numbers, symbols and operators (such as + and ×) grouped together that show the value of something.
Algorithm An Algorithm is a step-by-step solution to a problem. It is like a cooking recipe for mathematics. Example: one Algorithm for adding two digit numbers is "add the units, add the tens and combine
Coefficient A number used to multiply a variable
Simplify Simplify the fraction (if needed)
Evaluate to ascertain the numerical value of (a function, relation, etc.).
Like Term Like Terms more ... Terms whose variables
Constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.
Linear Equation an equation between two variables that gives a straight line when plotted on a graph..
Nonlinear equation In physics and other sciences, a nonlinear system is the opposite of a linear system, that is a system that does not satisfy the superposition principle, which means that the output is not directly proportional to the input
Quadratic involving the second and no higher power of an unknown quantity or variable.: "a quadratic equation".
Function a relationship or expression involving one or more variables.: "the function (bx + c)".
Inequality difference in size, degree, circumstances, etc.; lack of equality.: "social inequality" "the widening inequalities in income".
Slope The Slope (also called Gradient ) of a straight line shows how steep a straight line is.
Quadrant Any of the 4 equal areas made by dividing a plane by an x and y axis
Coordinate Plane The Plane containing the "x" axis and "y" axis. See: Axis (graph) Cartesian Coordinates
Standard Form Another name for "Scientific Notation", where a number is written in two parts:
Slope-Intercept Form The General Form is not always the most useful Form, and you may prefer to use: The Slope-Intercept Form of the equation of a straight line:
Variable A symbol for a number we don't know yet. It is usually a letter like x or y. Example: in x + 2 = 6, x is the Variable If it is not a Variable it is called a Constant See: Constant
X- intercept X- intercept x Intercept of a Straight Line The x Intercept of a straight line is simply where the line crosses the Y axis.
Y-Intercept Y Intercept of a Straight Line The Y Intercept of a straight line is simply where the line crosses the x axis.
