Write terms with equal exponents together. Always write in random order of exponent value with variables in the middle.2 Variables at end. Write terms with smallest exponents first. Always write in ascending order of exponent value with variables at the end.3 Constants at end. Write terms with the largest exponents first. Always write in descending order of exponent value with constants at the end.4 Variables in the Middle. Write terms with negative exponents first. Always write in ascending order of exponent value with variables at the beginning.Don't know?

Continuous dataHas values within a range, measured not counted, does not have gaps between data points (data is connected lines or curves).Example of discrete dataDays of the week ExpressionsA group of symbols such as numbers and operators that has mathematical validity CommutativeThe order in which the numbers appear in the sum can be reversed Identity propertyAdding 0 to any number does not change the original number Additive inverseValues that are equally far from 0 on the number line.NegativeWhen multiplying a positive number by a negative number the result is always PositiveMultiplying a negative number by a negative number results in a positive FactorsIntegers that evenly divide the initial integer Prime numberPositive integer with exactly two positive factors consisting of 1 and itself Composite numberHas at least one positive factor other than one and itself FactorizationProcess of breaking up a composite number into its prime factors fundamental theorem of arithmeticAny integer greater than one is either Prime or the product of Prime numbers Principal square rootPositive square root of a number RadicanNumber under radical sign √16=4 Open CircleRepresents less than or greatest than on the number line Perfect squareProduct of any integer with itself yields a perfect square.Whole numberspositive numbers with a whole value IntegersNumbers with no fractions or decimal value but can be positive or negative Rational numbersNumbers that can be expressed as a fraction or decimal values that have that end or repeat forever. Includes all integers since all integers can be expressed as fractions.Real numbersEverything that can be included in a number line including pi.FractionsExpress numbers which are part of a whole NumeratorNumber written before the slash or above the fraction bar

Proper fractionNumerator is less than denominator and the value of the fraction is less than one Improper fractionNumerator is greater than denominator and therefore is greater than one except with negative fractions Mixed numbersA whole number and proper fraction. A negative sign in front applies to both parts of the mixed number.MultiplesIntegers created by multiplying one number times another number FractionsExpress numbers which are part of a whole NumeratorNumber written before the slash or above the fraction bar Proper fractionNumerator is less than denominator and the value of the fraction is less than one Improper fractionNumerator is greater than denominator and therefore is greater than one except with negative fractions Mixed numbersA whole number and proper fraction. A negative sign in front applies to both parts of the mixed number.MultiplesIntegers created by multiplying one number times another number ReciprocalThe number which of multiplied by divisor gives you one (like the fraction flipped over) Terminal decimalHas digits that end RatioComparison of two numbers RateA ratio that compares two quantities having different units of measure ProportionTrue statement in which two ratios are equal to each other. Two days are proportional of they are equivalent.Conditional proportionOne part of a proportion is a variable or unknown quantity Celsius to FahrenheitCelsius x 9/5 + 32 Fahrenheit to Celsius(Fahrenheit - 32) x 5/9 ConstantNumber with a fixed value. All real numbers are constants Elementary operationsAddition, subtraction, multiplication, division BaseThe number an exponent is written next to

VariableSymbol that represents our holds the place of a numerical value CoefficientA number by which a variable is being multiplied. Coefficients are written in front of variables. 16x, 16 is coefficient. If there is no number you assume an invisible1.TermCan be a single constant, a single, or a number of constants and variables multiplied together.Algebraic expressionString of terms connected by division, addition, and subtraction.How to write an algebraic expressionConstants at end. Write terms with the largest exponents first. Always write in descending order of exponent value with constants at the end.Inverse operationOperations that undo each other. Subtraction is inverse of addition. Division is inverse of multiplication.Like termsHave the same variable with the same exponent Degree of an expressionRefers to largest exponent in an expression LinearHas degree of 1 QuadraticHas degree of 2 CubicHas degree of 3 ConstantHas degree of 0 Distributive propertyPrinciple used to multiply a single term by multiple terms. If there are parenthesis around multiple terms which are in turn multiplied by a single term, we can use this property.
