Parallel
A pair of lines
with same slope that will never meet.
Parallelogram
A Parallelogram
is a quadrilateral with two pairs of parallel sides.
Parentheses
Round brackets
appear as a pair.
Percentage
A ratio expressed
with a denominator of 100.
Perfect square
An integer that
is the square of another integer, such as 1, 4, 9. ...etc. For example,
49 is a perfect square number, since 49 = 7^{2 .}
Perpendicular
Two
lines intersect at a right angle are perpendicular to each other.
The slope of one line is negative reciprocal of the other.
Pi
The ratio of
the circumference of any circle to its own diameter, denoted by
. It is a transcendental number
and approximately equal to 3.14.
Place
value
The place value
of a digit of a number in a counting system denotes the location
of that digit and is represented by a power of the base of that
counting system. For example, units, tens, hundreds, etc. in the
decimal system.
Plot
Connect points
on a graph relative to a coordinate system.
Plus
Plus is an addition
operation.
Polygon
A closed plane
figure bounded by three or more straight line segments that terminate
in pairs at the same number of vertices, and do not intersect other
than at their vertices.
Polynomial
An expression
containing two or more terms, such as .
Positive
value
Having a value
greater than zero.
Prime
number
A natural number
having no factors other than 1 and itself, such as 3,5,7,11 etc.
Product
The result of
multiplication of two or more numbers.
Property
of real numbers
For any real
numbers a,b, & c the following properties are valid.
i) For addiction:
Commutative:
a + b = b + a
Associative
Law: (a + b) + c = a + (b +c)
Additive Identity:
a + 0 = a
Aditive Inverse
(opposite): a + (a) = 0
ii) For multiplication:
Commutative
Law: ab = ba
Associative
Law: (ab)c=a(bc)
Multiplicative
Identity: a1= 1 a = a
Mutiplicative
Inverse (reciprocal): a (1/a) = (1/a) a = 1
