Base | (1)A number that is raised to an exponent; (2) a particular side or face of a geometric figure; (3) a number that is multiplied by a rate or of which a percentage or fraction is calculated. Example: (1) 23, where 2 is the base and 3 is the exponent |
Base Ten Number System | A place value number system in which ten digits, 0 through 9, are used to represent a number and the value of each place is 10 times the value of the place to its right; the value of any digit in the number is the product of that digit and its place value. Examples: 10 ones = 1 ten, 10 tenths = 1 one, 10 tens = 1 hundred, 10 hundredths = 1 tenth, 10 hundreds =1 thousand, 10 thousandths = 1 hundredth, 10 thousands = 1 ten thousand, 10 ten-thousandths = 1 thousandth |
Basic Whole Number Facts | Addition, subtraction, multiplication, or division of all combinations of two numbers, using the numbers 0–9. (Sometimes the numbers 10–12 are included in the basic whole number facts.) |
Before | In front of, earlier than, at an earlier time. |
Between | In the middle of two numbers; greater than the first number but less than the second number (e.g., 17 is between 16 and 18). |
Billion | One thousand million (in the U.S.). 1,000,000,000. |
Binomial | An algebraic expression consisting of two terms (9a + 4). You could also say that it is an expression that is a sum or difference of two monomials. (Also see Monomial) |
Binomial Distribution | In probability, a binomial distribution gives the probabilities of k outcomes A (or n-k outcomes B) in n independent trials for a two-outcome experiment in which the possible outcomes are denoted A and B. |
Binomial Expression | When you study algebra you will learn about binomial expressions. It is an expression that uses two terms. |
Binomial Theorem | In mathematics, a theorem that specifies the complete expansion of a binomial raised to any positive integer power. |
Bisect | To divide a geometric figure into two congruent parts. |
Bisector | A line segment, ray, line, or plane that divides a geometric figure into two congruent halves. |
Bit | A <b>bit</b> is a specific amount of information found in computers. Bytes, kilobytes, megabytes and gigabytes are all increasing levels of bits. A <b>bit</b> is the smallest piece of computer memory. It is either 1 or 0, on or off. It is exactly one-eighth. |
Box Plot | A graphic method that shows the distribution of a set of data by using the median, quartiles, and the extremes of the data set. The box shows the middle 50% of the data; the longer the box, the greater the spread of the data. spread of the data. |
Box-and-Whisker Plot | A graphical method for showing the median, quartiles, and extremes of data. A box plot shows where the data are spread out and where they are concentrated. |
