adding integers

SAME SIGNS- add the numbers and keep the sign DIFFERENT SIGNS- subtract and keep the sign of the larger number

cross canceling

dividing the denominator and the numerator by the same number

Linear function

y=x or f(x)=x and streight line

Variable

a quantity that can assume any of a set of values

Coefficient

number like 7,6,ect

dividing integers

same rule

Like terms

terms that have indentical variables and exponents

Unlike terms

terms where either the base or the exponents are different

Arithmetic function

ADDITION OR SUBTRACTION

Add,Plus,Sum,More than, Increased by are all words for

Addition

Changing the grouping of numbers will NOT change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication

Associative Property

Tell which property 2+(7+8)=(2+7)+8

Associative Property

Tell which property 23=32

Commutative Property

Tell which property 96=69

Commutative Property

The order of two numbers may be switched around and the answer is the same.

Commutative Property

solving equations containing decimals

Decimals can be eliminated by multiplying both sides of the equation by the LCD of all the decimals.

a property indicating a special way in which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses, such as a(b + c) = ab + ac

Distributive Property

Tell which property 3(6+2) = 3•6+ 2

Distributive property

Tell which property 25•1=25

Identity Property

adding or multiplying by these numbers does not change the answer

Identity Property

adding decimals

Line up the decimal points and add normally (ex. 23.62+8.369=31.989)

subtracting decimals

Line up the decimal points and subtract normally (ex. 20.02-1.36=18.66)

dividing decimals

Move the decimal in the number outside the box over as many places as you need to to make it a whole number. Then do the same with the number inside the box. If the 2nd number still has a decimal, bring it up and divide normally

times,Multiplied by, Product, Are all words for

Multiplication

use decimal to solve

Ok

dividing decimals by integers

Place the decimal point in the quotient directly above the decimal point in the dicidend

subtract, Minus, Difference,Less than, decreased by, take away, less are all words for

Subtract

absolute value

The distance a number is from zero on a number line

adding fractions

To add or subtract fraction, first find a common denominator, then add or subtract the numerators

multiplying integers

if the numbers have the same sign, the product will be positive. if the numbers have different signs, the product will be negative.

subtracting fractions

line them up vertically,make sure they have common denominators and make sure it is in lowest terms

geometric function

multiplication or division

multiplying decimals

Multiply or divide the number just as you would without decimals. You dont have to line up the decimals; add up all the decimal places in all the numbers, and that's where you put the decinal in the answer.

Integers

Whole numbers and their opposites

FINAL QUESTION WILL YOU GET AN A

YES I WILL

Divided into, Divided by, Quotient are all words for

Division

subtracting Integers

Follows same rules

Equivalent fractions

Fractions that name the same amount

Solving equations

The process of applying algebraic properties of equality to isolate a variable. For example, to solve 2x = 6, we apply the division property of equality by dividing both sides by 2, giving us x = 3. In solving equalities "whatever you do to one side, you do to the other" to keep the equation in balance

multiplying fractions

To multiply fractions, multiply the numerators and multiply the denominators
