||A fraction that has its numerator of the larger than the denominator.
Example: 25/12, 3/2, etc.
||An equation written with a greater than, a less than sign, or a not equal to sign. Basically, an equation without an equals sign.

Example: -3, -2, -1, 0, 1, 2, 3,...
||An infinite path connecting an infinite number of points. A linear line is perfectly straight (diagonal/verticle/horizontal.)
||The power to which a number is raised - the exponent.
||A whole number and a fraction.
||The repeated addition of a number.
Example: 4x4 = (4+4+4+4) = 16.
||Logarithm with base e
Example: ln 5
||Any positive, whole number.
Example: 1, 2, 3, 4,...
||The top number in a fraction.
Example: 4/5; 4 is the numerator.
||An eight-sided polygon.
||Set of points equal distance from a focus and a directrix.
||Two (or more) lines that will never intersect. (Lines with the same slope.)
Examples: Y = 3/4x + 2 and Y = 3/4x + 5 are parallel lines.

||A location with no dimensions, shape, or size.
||A closed figure with at least four sides and four angles.
||Any integer that cannot be divided by another number evenly except by itself and 1.
Examples: 2, 3, 5, 7, 11, 13,...
||The result of multiplying two or more numbers together.
Example: 4x4=16; 16 is the product.

||One quarter (1/4) of a coordinate plane axis.
||A four-sided polygon.
||The answer of one number divided by another.
Example: 33÷3 = 11; 11 is the quotient.
