Basic probability: #of total come\# of total outcome in the sample
space
1. P(B | A): conditional probability
2. P(A and B)=P(A) • P(B): multiplication rule- independent events
3. P(A and B)= P(A) • P(B|A): multiplication rule- dependent events
4. P(A or B)= P(A) + P(B): addition rule- Disjoint
5. P(A or B)= P(A) + P(B) - P(A and B): addition rule- non-Disjoint
6. product: The result of multiplying values.
7. factorization: The process of determining the prime factors of a
composite number.
8.integer: "A number, (positive, negative, or zero), that can be
represented without a fractional or a decimal component."
9. superscript: A symbol (such as a number or letter) written above
and imme- diately to the left or right of another character.
10.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."
11.expression: "A string of terms that are connected by division,
addition, and subtraction operations."
12.addition: Finding the total of two or more values.
13.interval: A set of numbers between two specified values.
14.difference: The result of one number being subtracted from another
number.
15.multi-step expression: An expression or equation with more than
two values and two or more operators that requires multiple steps to
be solved.
16.discrete: "A collection of numbers whose values are distinct,
separate, and unconnected."
,17.negative number: "A number whose value is less than zero. On the
number line, they are to the left of zero."
18.division: Splitting values into equal parts or groups.
19.estimation: Approximating a value for a calculation
20.radical sign: The symbol which indicates to take the square root of
the number that follows.
21.numbers: A word or symbol (such as 'five' or '16') that represents
a specific amount or quantity.
, 22.exponents: "Sometimes called a power, it is a quantity that
represents repeat- ed multiplication."
23.parentheses: "In mathematics, these () are used to separate
operations within an expression. Any operations that lie within
parentheses should be performed first."
24.real number: "Any numbers on the number line. They include zero,
negative and positive integers, fractions, and decimals."
25.sum: The result of multiple numbers being added together.
26.square root: A number that produces a specified number when it is
multiplied by itself.
27.Fundamental Theorem of Arithmetic: A concept which states that any
inte- ger greater than 1 is either prime or is the product of a unique set
of prime numbers.
28.prime number: A number with only two factors: one and itself.
29.operator: A word or symbol (such as + or -) that indicates an
operation between values.
30.principal square root: "The positive square root of a number. For
example, the principal square root of 36 is 6."
31.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.
32.positive number: "A number whose value is greater than zero. On
the number line, these numbers are to the right of zero."
33.additive inverse: "Two numbers equidistant from 0 on a number
line whose sum is 0. For example, 3 and -3
34.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.
35.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."
36.negative square root: "The negative compliment of a perfect
square. For example, -6 is the this of 36."
37.operation: "In mathematics, this is a procedure which generates a
new value from one or more operands, or mathematical values."
