# 6th Math Unit 4

### Modules 10, 11, 12, I will add 13, 14 later

TermDefinition
addition property of equality – the property that explains that you can add the same number to both sides of an equation, and the two sides will remain equal.
algebraic expression – an expression that contains at least one variable.
associative property – (ADDITION/MULTIPLICATION) the property that states when adding/multiplying groups of numbers, the grouping of the numbers does not change the value…. order does not matter
base - when a number is raised to a power, the number that is used as a factor is the base
coefficient – the number that is multiplied by the variable in an algebraic expression.
commutative property – (ADDING / MULTIPLICATION) the property that states that changing the order of the numbers does not change the value –
constant – a value that does not change
distributive property – the property that states if you multiply a sum by a number, you will get the same result if you multiply each addend by that number and then add the products.
division property of equality – the property that states that you can divide both sides of an equation by the same nonzero number, and the two sides will remain equal.
division property of inequality – the property that states that you can divide both sides of an inequality by the same positive number, and the inequality will remain true.
equation – a mathematical sentence that shows that two expressions are equivalent
equivalent expression – have the same value for all values of the variables
exponent - the number that indicates how many times the base is used as a factor.
factor - a number that is multiplied by another number to get a product
identity property of addition:– the adding of zero to a number does not change its value.
identity property of multiplication:– the multiplying a number by one does not change its value.
inverse property – the property that states the sum of a number and its opposite, or additive inverse, is zero
like terms – terms with the same variables raised to the same exponents
multiplication property of equality – the property that states that you can multiply both sides of an equation by the same number, and the two sides will remain equal.
multiplication property of inequality – the property that states that you can multiply both sides of an inequality by the same positive number, and the inequality will remain true.
order of operations – a rule for evaluating expressions: P E M/D A/S parentheses, compute powers and roots, then perform all multiplication and division from left to right, and then perform all addition and subtraction from left to right.
power - a number produced by raising a base to an exponent.
prime factorization - a number written as the product of its prime factors.
solution – the value of a variable that makes the equation true
subtraction property of equality – the property that explains that you can subtract the same number from both sides of an equation, and the two sides will remain the same
terms – the part of the expression that are separated by + or - signs
variable – a symbol used to represent a quantity that can change.
