multiples of a number
A number multiplied by various integers
percent increase formula
percent increase = (amount of increase/original whole) x 100%
estimation
a rough calculation of the value, number, quantity, or extent of something.
percent
A ratio comparing a number to 100( parts per hundred)
numerator
the top number in a fraction
variable term
numeric values consisting of variables and coefficients or constants
legend
A list that identifies patterns, symbols, or colors used in a chart
constant
a number that has a fixed value in a given situation; a characteristic or value that does not change
denominator
The bottom number in a fraction
inequality symbols
symbols used to show the order of two real numbers. less than < greater than > less than or equal to <_ greater than or equal to >_
non-negative
Greater than or equal to zero (positive or zero)
multiplication and division
addition of a number to itself a specified number of times separation of numbers into parts; the inverse of multiplication
scale
the ratio between the actual size of something and a representation of it
order of operations
the order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction pemdas
mixed number
A number made up of a whole number that is not zero and a fraction.
combine like terms
simplifying an expression by using the distributive property
rational number
A number that can be written as a fraction
proportion
An equation stating that two ratios are equal
metric system
The decimal measuring system based on the meter, liter, and gram as units of length, capacity, and weight or mass. (based on powers of ten)
rate
A ratio that compares two quantities measured in different units
irrational numbers
a real number that cannot be expressed as a ratio of two integers. (terminating or repeating decimals)
simplify
Reducing a fraction or an expression to a simpler form by actions such as cancellation of common factors and regrouping of terms with the same variable
algebraic equation
a number sentence that contains an equal sign and algebraic expressions - ex. y + 2 = 5
Rounding Rules
Round to the nearest TENTH means you keep ONE decimal place EX 0.5648 rounds to 0.6 The 6 behind the five tells the 5 to go up. Round to the nearest HUNDRETH means to keep TWO decimal places EX 0.56 The 4 tells the 6 to stay the same.
Bivariate
a set of data that has two variables
ratio
a comparison of the. size of two numbers
fraction
A number expressed as a numerator and denominator
constant of proportionality
the constant value of the ratio of two proportional quantities x and y
axis
A reference line from which distances or angles are measured in a coordinate grid. (plural - axes)
reciprocal
one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2
graph
a drawing illustrating the relations between certain quantities plotted with reference to a set of axes
Percent decrease formula
[(original value-new value)/original value] x 100
inequality
a mathematical statement with two expressions that do not have the same value A statement that compares two quantities using <, >, ≤,≥, or ≠
Integer
All whole numbers (both positive and negative) and zero.
expression
A mathematical phrase that contains operations, numbers, and/or variables. that are grouped to show a value
variable
A letter, often x,y,or z, that stands for an unspecified quantity
Word problem vocabulary:
less than (-), is (=), product(•), quotient (÷) * contextual= related to surrounding content *erroneous= incorrect *extraneous= irrelevant *operation= a mathematical action *repeat= do again *solution= the answer terminate= to end * solve= find the answer *sum= total of two or more values
decimal place value
Powers of ten by position away from the decimal point. Going left: units, tens, hundreds, etc. Going right: tenths, hundredths, thousandths, etc.
equation
A mathematical sentence that shows that two expressions are equivalent
place value
The value of a digit based on its position within a number
rate of change
A rate that describes how one quantity changes in relation to another
ordering numbers
Putting numbers in order of lowest to highest
chart
Information in the form of a table or graph
Cartesian Coordinate
an ordered pair or ordered triple used to specify a point on a plane or space, respectively
whole numbers
Natural numbers ( counting numbers) and zero; 0, 1, 2, 3...
decimal point
A number with one or more digits to the right of the decimal point .9
Inverse arithmetic operations
Mathematic operations that undo each other
common denominator
in a set of two or more fractions, an integer that is divisible by each denominator. That is, a multiple of all of the denominators
unit rate
a rate which shows how many units of one quantity(in the numerator) correspond to one unit of the second quantity( in the denominator) such as miles/hour
addition and subtraction
calculation of a total of two or more numbers removing one number from another the inverse of addition
