Key Concepts:
Terms in this set (50)
rational numbers
decimals, fractions and integers. written in the form a/b, where a and b are both integers, but b is not zero, can be located on the number line
whole number
numbers that are not fractions, decimals, nor negative numbers, rather counting numbers like 0,1, 2, 3, 4, 5...
absolute value
a number's distance from zero, always positive
opposites
numbers that are the same distance from zero like nine and negative nine
median
middle value in an ordered data set
repeating decimal
a decimal that has a recurring number or pattern of numbers that continues
area
the amount of space within a figure
perimeter
the distance around a figure like a border
volume
the amount of 3-D space an object occupies, also its capacity or how much it can hold
inverse operation
to use the opposite operation such as the inverse of multiplication is division
evaluate
to solve a problem
variable
a letter or symbol that represents one or more numbers
distributive property
multiplying a number by a group of numbers added together is the same as doing each multiplication separately. 3(2 + 4) = 3×2 + 3×4
coordinate plane
two perpendicular number lines that form the x and y-axis used to plot a location of a point
Reciprocal
When you multiply a number by its "Multiplicative Inverse" you get 1.
Example: 8 × (1/8) = 1
ordered pair
Two numbers written in a certain order.
Usually written in parentheses like this: (2,3)
Can be used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second.
Here the point (2,3) is 2 units along, and 3 units up.
mode
the number that occurs the most in a set of scores, values or numbers
percent
Percent means parts per 100
The symbol is %
Example: 25% means 25 per 100
fraction
Part of a whole.
• the bottom number (the denominator) says how many parts the whole is divided into
• the top number (the numerator) says how many parts we have.
like terms
In an expression, terms that are all constants or that have the same variable and power.
difference
the answer to a subtraction problem
product
the answer to a multiplication problem
sum
the answer to an addition problem
quotient
the answer to a division problem
dividend
the number being divided
divisor
the number that does the dividing
factors
a whole number that divides another number equally, for example, four and five are factors of twenty
multiples
sequence of products using the same base number multiplied by different numbers. For example, the multiples of nine include: 9; 18; 27; 36...
exponent
the number of times a base number is multiplied by itself.
equation
statement that uses an = sign to show that two expressions have the same value.
example: 2+3=5
coefficient
a number multiplied by a variable in an expression
constant
a value in an expression that does not change
term
a constant number, a variable, or a grouping of numbers and variables in an expression.
greatest common factor (GCF)
the largest whole number that divides two or more numbers exactly. For example, 6 is the GCF of 24 and 42.
least common multiple (LCM)
the smallest number that is a multiple of two or more numbers. For example 12 is the LCM of 6 and 12.
even number
any number ending in 0, 2, 4, 6, or 8
odd number
any number ending in 1, 3, 5, 7, or 9
outlier
a value that is far from a majority of values in a data set
mean
the average of a set of numbers found by adding all of the numbers and dividing by the amount of numbers in the set.
ratio
a comparison of two or more amounts
proportion
two ratios that are equivalent
unit Rate / unit Price
quantity or cost per one item
substitute
to replace variable with a number
surface area
the total area of the faces or other surfaces of a solid shape.
quadrants
the four regions of the coordinate plane, formed by the intersection of the x-axes and y-axes.
simplest form
when the the GCF of a fraction's numerator and denominator is one
range
in a set of data, the difference between the minimum and maximum values.
commutative property
in addition and multiplication the order of the numbers does not affect the answer for example 6 times 5 is the same as 5 times 6
origin
the point where the x and y-axis intersect
net
a two dimensional pattern that can be folded to create a three-dimensional shape
