An adjective frequently associated with the concept of “nothing“, though it’s usually attached to a noun to mean something more specific. For example: A null element is an element that generalizes the concept of zero (e.g., null matrix). A null vector is the vector of length 0 (among other meanings).

angle A figure formed by two rays or two line segments with a common endpoint called the vertex of the angle. The rays or segments are called the sides of the angle. An angle is measured in degrees between 0 and 360. One side of an angle is the rotation image of the other side through a number of degrees.

A variable is a symbol that we assign to an unknown value. It is usually represented by letters such asx, y, or t. For example, we might say that l stands for the length of a rectangle and w stands for thewidth of the rectangle. We use variables when we need to indicate how objects are related even though we may not know the exactvalues of the obje...
The coefficient of a variableis the number that is placed in front of a variable. For example, 3 × w can be written as 3w and 3 is the coefficient. Coefficient
A term can be any of the following: 1. a constant: e.g. 3, 10, π, 2. the product of a number (coefficient) and a variable: e.g. –3x, 11y, 3. the product of two or more variables: e.g. x2, xy, 2y2, 7xy Like terms are terms that differ only in their numerical coefficients.For example: 3a, 22a,are like terms.
An equation consists of two expressionsseparated by an equal sign. The expression on oneside of the equal sign has the same value as the expression on the other side. For Example: 4 + 6 = 5 × 2 l = 3 × w 3w + 4xy + 5 = 2w + 3
A Quadratic Equation is an equation of the form: ax2+ bx + c = 0, where a, b and c are numbers and a ≠ 0 For Example: x2 + 2x + 3 = 0 2x2 + 5x – 7 = 0 2x2 + 5x = 8 (is a quadratic equation because it can be changed to 2x2) + 5x – 8 = 0 x2 + x = 0 (is a quadratic with c = 0) 2x2 – 7 = 0 (is a quadratic with b = 0) 2x + 3 = 0 (is not a quadratic beca...
