Title  Description  

Base (Exponential)  Any value that is raised to a power is termed a base value. That power is typically expressed as an exponent, and that exponent could be an integer, a decimal value, or a fraction. The base is the number or expression being raised to the power of the exponent. 

Base, Geometric  For a polygon, the line segment on the bottom. For a solid, the area of the "floor." 

Bearing  The direction of a vector can be a heading or a bearing. Heading implies movement along a compass direction. Bearing implies a static compass direction. 

Beta  Beta is the second letter of the Greek alphabet.  
Biconditional  A biconditional statement has literally two conditions. The classic IfThen statement is the biconditional with a hypothesis and conclusion. 

Binomial  A binomial has two terms. Terms are usually separated by plus signs or minus signs. 

Binomial Coefficients  Binomial coefficients are found in Pascal's Triangle. We use these coefficients to raise binomials to successive powers as well as to determine the number of combinations or ways we can take a number of objects from a set of objects. 

Binomial Probability  When outcomes are of a binary nature, the logic of two states (high or low, true or false, or the ones and zeroes of computer data streams) we can employ techniques of binomial probability, with coefficients from Pascal's Triangle, to determine the likelihood of potential events or outcomes.  
Binomial Theorem  The Binomial Theorem affords the use of coefficients to calculate probabilities that are determined with the logic of two states. In situations where outcomes are either true or false, high or low, or the 1 or 0 of binary data streams, the Binomial Theorem gives us efficient calculations for likelihoods of events. 

Bisect  Infinite lengths are not bisected. We bisect, or divide into equal halves, angles or line segments. Rays and lines are not bisected. 

Bisector  A bisector cuts a geometric entity into two equal halves. It may divide an angle or a line segment, depending on the specific circumstance. A perpendicular bisector divides a line segment at a right angle. 

Boundary  Some functions are bounded, some are not. Some regions are bounded, some are not. To be bounded means to have a limit; its extent only goes so far, and then it stops or ends. 

Bounded Function  A bounded function approaches or reaches a limit. If a function goes toward infinity it is generally considered unbounded. 

BoxandWhisker Plot  In statistical data, a boxandwhisker plot is sometimes used to graphically represent quartiles. Quartiles are the extremes of the body of data, as well as the 25th, 50th and 75 percentiles. 

Braces  Braces act just like parentheses. Always (almost) used in pairs, braces look like this: { }. 

Brackets  Brackets act just like parentheses, coming in pairs to group data or terms.
