C955 All Terms and FormulasBasic probability - -#of total come\# of total outcome in the sample space
-P(B | A) - -conditional probability
-P(A and B)=P(A) • P(B) - -multiplication rule- independent events
-P(A and B)= P(A) • P(B|A) - -multiplication rule- dependent events
-P(A or B)= P(A) + P(B) - -addition rule- Disjoint
-P(A or B)= P(A) + P(B) - P(A and B) - -addition rule- non-Disjoint
-product - -The result of multiplying values.
-factorization - -The process of determining the prime factors of a
composite number.
-integer - -"A number, (positive, negative, or zero), that can be represented
without a fractional or a decimal component."
-superscript - -A symbol (such as a number or letter) written above and
immediately to the left or right of another character.
-perfect square - -"The product of any integer with itself. . So, a number is a
this if it can be written as the square of an integer. For example, 3 * 3 = 9."
-expression - -"A string of terms that are connected by division, addition,
and subtraction operations."
-addition - -Finding the total of two or more values.
-interval - -A set of numbers between two specified values.
-difference - -The result of one number being subtracted from another
number.
-multi-step expression - -An expression or equation with more than two
values and two or more operators that requires multiple steps to be solved.
-discrete - -"A collection of numbers whose values are distinct, separate,
and unconnected."
, -negative number - -"A number whose value is less than zero. On the
number line, they are to the left of zero."
-division - -Splitting values into equal parts or groups.
-estimation - -Approximating a value for a calculation
-radical sign - -The symbol which indicates to take the square root of the
number that follows.
-numbers - -A word or symbol (such as 'five' or '16') that represents a
specific amount or quantity.
-exponents - -"Sometimes called a power, it is a quantity that represents
repeated multiplication."
-parentheses - -"In mathematics, these () are used to separate operations
within an expression. Any operations that lie within parentheses should be
performed first."
-real number - -"Any numbers on the number line. They include zero,
negative and positive integers, fractions, and decimals."
-sum - -The result of multiple numbers being added together.
-square root - -A number that produces a specified number when it is
multiplied by itself.
-Fundamental Theorem of Arithmetic - -A concept which states that any
integer greater than 1 is either prime or is the product of a unique set of
prime numbers.
-prime number - -A number with only two factors: one and itself.
-operator - -A word or symbol (such as + or -) that indicates an operation
between values.
-principal square root - -"The positive square root of a number. For
example, the principal square root of 36 is 6."
-whole number - -A number whose value is 0 or greater (negative numbers
are not considered this), and can be represented without a fractional or a
decimal component.
-positive number - -"A number whose value is greater than zero. On the
number line, these numbers are to the right of zero."
, -additive inverse - -"Two numbers equidistant from 0 on a number line
whose sum is 0. For example, 3 and -3
-commutative - -The property that the order of the numbers under the
operation does not change the result. Addition and multiplication are this: a
+ b = b + a and ab = ba.
-multiplicative inverse - -"opposite of a number x is the number you must
multiply x by to get 1. For example, 5 and 1/5 are this."
-negative square root - -"The negative compliment of a perfect square. For
example, -6 is the this of 36."
-operation - -"In mathematics, this is a procedure which generates a new
value from one or more operands, or mathematical values."
-identity property - -"The property that 0 can be added to any number
without changing the value of the number. Likewise, 1 can be multiplied by
any number without changing the value of that number."
-rational number - -"This type of number is a number that can be written as
a ratio of integers, which means it can be written as a fraction."
-order of operations - -A set of rules that defines the order in which
mathematical operations should be performed
-associative property - -"This property holds that under certain operations in
a multi-step expression, the computations may be done in any order.
Commonly represented as (a + b) + c = a + (b + c). Addition and
multiplication follow this property"
-prime factorization - -Determining the set of prime numbers whose product
is the original integer.
-continuous - -A collection of numbers whose values are not dividable into
distinct units.
-composite number - -A number with more factors than just one and itself.
-multiplication - -"In mathematics, this is the act of adding the same
number multiple times. It is often denoted by the dot sign, ·."
-base number - -"The number multiplied by itself when paired with an
exponent. For example, in 8 to the third power, 8 would be this number."
