Example of discrete data - correct answer Days of the week Expressions - correct answer A group of symbols such as numbers and operators that has mathematical validity Commutative - correct answer The order in which the numbers appear in the sum can be reversed Identity property - correct answer Adding 0 to any number does not change the original number Additive inverse - correct answer Values that are equally far from 0 on the number line. Negative - correct answer When multiplying a positive number by a negative number the result is always Positive - correct answer Multiplying a negative number by a negative number results in a positive Factors - correct answer Integers that evenly divide the initial integer Prime number - correct answer Positive integer with exactly two positive factors consisting of 1 and itself Composite number - correct answer Has at least one positive factor other than one and itself Factorization - correct answer Process of breaking up a composite number into its prime factors fundamental theorem of arithmetic - correct answer Any integer greater than one is either Prime or the product of Prime numbers Principal square root - correct answer Positive square root of a number Radican - correct answer Number under radical sign √16=4 Open Circle - correct answer Represents less than or greatest than on the number line Perfect square - correct answer Product of any integer with itself yields a perfect square. Whole numbers - correct answer positive numbers with a whole value Integers - correct answer Numbers with no fractions or decimal value but can be positive or negative Rational numbers - correct answer Numbers 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 numbers - correct answer Everything that can be included in a number line including pi. Fractions - correct answer Express numbers which are part of a whole Numerator - correct answer Number written before the slash or above the fraction bar Proper fraction - correct answer Numerator is less than denominator and the value of the fraction is less than one Improper fraction - correct answer Numerator is greater than denominator and therefore is greater than one except with negative fractions
