undefined, object

copy deck

- combining like terms
- adding or subtracting the terms with the same variables or constant terms together
- subtraction
- difference, minus, subtracted from, less than, decreased by, less
- Quotient of Different Signs
- (+)(-)= - or (-)(+)= -
- terms
- the addends of an algebraic expression
- first-degree equations in one variable
- the exponent is 1,there is only one variable and it is not below a fraction bar
- integers
- consist of the numbers labeled on the number line (whole numbers)
- subtracting integers
- change the sign to addition and change the sign behind to the oppostite
- additive inverse
- another name for the opposite of a number
- expression
- can be simplfied, but not solved
- when crossing the equal sign
- do the opposite function (adding/subtracting & multiplying/dividing)
- absolute value
- the number's distance from 0 on the number line
- <
- "less than" symbol, to the left of
- Product of Like Signs
- (+)(+)=+ or (-)(-)= -
- variable term
- a term that contains a variable
- equals sign
- equals, gives, is/was, yields, amounts to, is equal to
- commutative property
- when adding, numbers order can be switched around without changing the answer
- simplified
- when all like terms have been combined in an algebraic expression
- negative numbers
- numbers that extend to the left on the number line or less than 0
- simplify
- get terms in lowest possible
- solution
- a number that when subsituted for a variable makes the equation a true statement
- addition
- sum, plus, added to, more than, increased by, total
- >
- "greater than" symbol, to the right of
- like terms
- terms with the same coefficient
- what you do to one side of the equal sign
- you must do to the other
- Quotient of Like Signs
- (+)(+)=+ or (-)(-)= -
- positive numbers
- numbers that extend to the right on the number line or greater than 0
- adding different signed numbers
- larger absolute value minus the smaller absolute value, and keep sign of the larger number
- distributive property
- multiplication distributes over addition (and subtraction)
- associative property
- when adding, the numbers can be grouped differently without change the answer
- signed numbers
- positive numbers, negative numbers, and zero
- constant terms
- terms that are only a number
- equation
- has to have an equal sign and can be solved
- linear equations in one variable
- the exponent is 1,there is only one variable and it is not below a fraction bar
- equivalent equations
- have the same solution
- average
- (sum of numbers) / (number of numbers)
- multiplication
- product, times, multiply, twice, of, double
- numerical coefficient
- the number factor of a variable term
- PEMDAS
- order of operations, parentheses, exponents,multiplication, division, addition, subtraction
- opposite numbers
- same numbers with different signs
- multiplication property of equality
- the same number may be multiplied to or divided from both sides of an equation without changing the solution
- division
- quotient, divide, shared equally among, per, divided by, divided into
- opposites
- two numbers that are the same distance from 0 on the number line but opposite sides
- Product of Different Signs
- (+)(-)= - or (-)(+)= -
- addition property of equality
- the same number may be added to or subtracted from both sides of an equation without changing the solution
