Question | Answer |
possible outcomes | the events that have a chance of happening in a probability experiment |
prediction | a reasonable guess as to what will happen |
scientific notation | a number is written as the product of a number that is at least 1, but less than 10 and a power of 10 |
Addition Property of Equality | when you add the same number to both sides of an equation, the sides remain equal |
algebraic expression | an expression that includes at least one variable |
Associative Property | the way addends are groupsed or factors are grouped does not change the sum or the product |
Commutative Property | when the order of addends or factors is changed, the sum or product is the same |
Distributive Property of Multiplication | multiplying a sum by a number is the same as multiplying each addend by the number and then, adding the product |
Division Property of Equality | if you divide both sides of an equation by the same nonzero number, the sides remain equal |
equation | an algebraic or numerical sentence that shows that two quantities are equal |
solution | a value that, when substituted for a variable in an equation, makes the equation true |
Subtraction Property of Equality | if you subtract the same number from both sides of an equation, the sides remain equal |
variable | a letter or symbol that stands for a number or numbers |
expression | a mathematical phrase that combines operations, numbers, and/or variables |
formula | a set of symbols that expresses a mathematical rule |
Identity Property of One | the product of any number and 1, is that number |
Identity Property of Zero | the sum of any number and 0 is that number |
inequality | an algebraic or numberical sentence that shows that two amounts are not equal |
Multiplication Property of Equality | when you multiply both sides of an equation by the same number, the sides remain equal |
numerical expression | a mathematical phrase that uses only numbers and operation symbols |
order of operations | first perform the operations in parentheses, clear the exponents, perform all multiplication and division, and then perform all addition and subtraction |
