Bar
Graph
A diagram consisting
of a sequence of vertical or horizontal bars or rectangles, each
of which represents an equal interval of the values of a variable,
and has height proportional to quantities of the phenomenon under
consideration in that interval.
The following bar graph shows the incomes for two companies (the
blue one and the red one). The first six months of the year are
represented on the horizontal line (the x-axis) and the income (in
million dollars) for each corresponding month is on the vertical
line (the y-axis) represents .
Base
Base of a polygon
(triangle, parallelogram, ...) is one of its sides, usually the
one in the bottom.
Base of a solid (cube, pyramid, cylinder, cone, ...) is the area
of supporting the body, usually the one in the bottom.
Areas and Volumes
.
Billion
One thousand
million (109). In some countries means one million millions
(1012).
Binary
number
A number expressed
in place-value notation to base 2
Example:  represent
the number 5.
Binary
operation
An operation
that applies to two quantities resulted in a third quantity..
Example: Addition (difference, multiplication, ..) of real numbers.
Binary
relation
A relation explicitly
involving ordered pairs. For example: Let be R represent
the binary relation " is greater
than" then 
means 5 > 3
Bit
Abbreviation
for binary digit represented by 0 or 1.
Bound
A set of numbers,
denoted, S, is bounded if there exists two fixed real numbers, L
and U, such that L < x < U, for every x in S. For example,
the set {1+1/n}, where n is positive integers, is bounded, for taking
L and U such that L < 1 and U > 2.
Bracket
Either of any
pair of symbols used to enclose a number of items that are to be
regarded as constituting a single expression. Removing
brackets is vital to reduce and simplify algebraic expressions.
Byte
A sequence of
bits, usually eight or sixteen, encoding a single piece of data
and processor together.
