A
member of the set of positive whole
numbers {1, 2, 3, . . . }, negative whole
numbers {-1, -2, -3, . . . }, and zero {0}.
A
number that can expressed exactly by a
ratio of two integers.
A
method for expressing a given quantity as a
number having significant digits necessary for
a specified degree of accuracy, multiplied by
10 to the appropriate power, as 1385.62
written as 1.386 × 10 3 .
A
rational number that is equal to the square
of another rational number.
A
number that cannot be exactly expressed
as a ratio of two integers.
A
rational number or the limit of a sequence
of rational numbers, as opposed to a
complex number.
 The
property that states that there always
exists another rational number between any
two given rational numbers. This means that
the set of rational numbers is dense.
 Two
angles that have the same vertex and a
side in common.
a
number or quantity placed (generally)
before and multiplying another quantity, as
3 in the expression 3x.
 The
distance between two points (x1, y1) and
(x2, y2) in the Cartesian coordinate system
can be given by: [(x1 - x2)2 + (y1 - y2)2]1/2.
 The
set of all possible input values for a
function or relation.
 The
side opposite the right angle in a right
triangle.
 Either
of the two sides that form the right
angle in a right triangle or one of the two
congruent sides in an isosceles triangle.
A
number that can be written as a fraction,
or as finite or repeating decimals.
 The
difference between the maximum and
minimum values in a set of data.
 Another
name for gradient.
A
method for expressing a given quantity as a
number having significant digits necessary for
a specified degree of accuracy, multiplied by
10 to the appropriate power, as 1385.62
written as 1.386 × 10 3 .
A
space figure with two parallel polygonal
bases that are the same shape and the same
size.
 Data
that is plotted as points on a graph to
show a possible relationship between two
sets of data.
 the
equation of a straight line in the form y =
mx + b where m is the slope of the line and b
is its y-intercept.
 The
magnitude of a number regardless of its
sign. Hence, the absolute value of a number
"n" is always positive or zero, written as |n|.
When the number "n" is represented on a
number line, its absolute value is the
distance from the origin to that number.
A
number used to indicate the number of
times a term is used as a factor to multiply
itself. The exponent is normally placed as a
superscript after the term.
 The
result obtained when multiplying
numbers, vectors, matrices, etc.
A
theorem stating that in a right triangle the
area of the square on the hypotenuse is
equal to the sum of the areas of the squares
drawn on the other two legs.
A
triangle in which all three interior angles
are acute (less than 90°).
The likelihood or chance of a given
event happening. It is often
expressed as a fraction or decimal.
The probability that m particular
events will occur out of a total of n
possible events is m/n. A certainty
means that, out of n possible
events, all the events (n events)
will happen. Therefore, a certainty
has a probability of 1 (n/n = 1).
Similarly, an impossibility has a
probability of 0 because none will
happen out of the total n possible
events (0/n = 0).
A
number that can divide into another
number with no remainder.
A
symbol that stands for an unknown
quantity. When we make a mathematics
equation out of an ordinary statement by
using a variable(s), it makes the thinking
process mechanized and automatic, thus
making the solution process much easier.
 Find
the value of an algebraic expression by
replacing the variable(s) with the correct
numerical value(s) to perform the operation.
 The
number resulting from division.
 An
angle with a measure between 0° and
90°.
 Planar
figures or solid shapes that have the
same shape and size.
A
number related to another in such a way
that when these two numbers are multiplied
together their product is 1.
A
point at which the two rays of an angle
meet or the intersection point of two sides of
a plane figure.
A
closed plane figure bounded by at least
three line segments.
A
triangle having no two sides equal.
 The
surface included within a closed figure,
measured by the number of square units
needed to cover the surface.
 The
length of the boundary around a shape
or a figure.
 The
boundary line of a circle or the length of
such a boundary line.
 An
angle that is between 90° and 180°.
A
pair of angles that add up to 90°.
A
eight-sided polygon. A regular octagon is a
polygon that has eight equal sides and eight
equal angles.
A
polygon with five sides.
A
triangle one of whose interior angles is
90°.
A
four-sided plane figure whose four sides
are equal.
 The
numerator and denominator of a fraction
that have had all common factors but 1
factored out and canceled.
A
line about which a curve or an object may
rotate or revolve.
