Ex: (1,2,3,4,etc...) Whole Number Are natural numbers and the number 0 (0,1,2,3,4,etc) Integers Includes positive numbers, zero, and negative numbers. Ex: (-1,0,1) Rational Number A number that can be written as a fraction with a numerator and a denominator that are integers. The decimal representation of a rational number either ends or repeats. Irrational Number a number that can NOT be expressed as a ratio of two integers or as a repeating or terminating decimal - Pi or any square root of an imperfect square are considered irrational Real Number All rational and irrational numbers. Any # on the number line. Imaginary Number i is the square root of -1 and/or i squared equals -1. Complex number a number of the form a+bi where a and b are real numbers and i is the square root of -1 Midpoint formula The midpoint is halfway between the two end points. Add both x coordinates then divide by 2. Add both y coordinates then divide by 2. Number Chart Factors Numbers that are multiplied together to get a product Prime Number A whole number that has exactly two factors, 1 and itself. Composite Number A number with more than two factors Prime Factorization Breaking down a composite number until all of the factors are prime Closed number system a system is closed under an operation if performing that operation on two elements of the system results in another element of that system. Ex: Integers are closed under addition, subtraction, multiplication but not division. Rational Numbers Closed They are closed under all operations (except division by 0) Real Numbers Closed and Complex Numbers Closed They are closed under all four operations. Irrational Numbers Closed Irrational numbers are NOT closed under ANY of the four operations communitive property With addition and multiplication, it does not matter what order the numbers are written, you still get the same result. Associative Property The way in which numbers are grouped does not change their sum or product Distributive Property a property indicating a special way in which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses, such as a(b + c) = ab + ac Identity of Multiplication a x 1 = a Identity of Addition a+0=a Inverse Element of Addition Inverse Property of Addition says that any number added to its opposite will equal zero. What is the opposite you might ask? All you have to do is change the sign from positive to negative or negative to positive. Example 1: 5 + (-5) = 0 -5 is the opposite of 5 Inverse Element of Multiplication says that any number multiplied by its reciprocal is equal to one. Example 1: 3/4 x 4/3 = 1 Absolute Value The distance a number is from zero on a number line a negative minus a positive add, and the answer will be negative (-5 - 3 = -8) a positive minus a negative add, and the answer will be positive; positive minus negative equals positve (2 - -3 = 5) negative minus negative Subtracting a negative number from a negative number - a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - -4. This would read "negative two minus negative 4". So we're changing the two negative signs into a positive, so the equation now becomes -2 + 4. Negative plus negative Equals a negative Negative plus positive or positive plus negative Keep the sign of the number with a larger absolute value negative times negative positive positive times negative negative negative divided by negative positive A positive divided by a negative negative PEMDAS Parentheses, Exponents, Multiplication, Division, Addition, Subtraction Order of Operations (PEMDAS) Always in ORDER from left to right feet in a mile 5280 feet yards in a mile 1760 yards grams in an ounce 28.35 ounces per pound 16 pounds per ton 2000 cups, pints, quarts and gallons What units do we use to measure customary capacity?

Subtracting with zeros Subtracting Decimals Multiplying decimals 1. Multiple numbers as if whole numbers. 2. Then count total number of decimal places in the factors and add them (Ex: 2.2 and 2.33 has three total decimal places) 3. Add the total number of Decimal places to product, counting left to right (Ex: 22*233 = 5126 -- 5.126 final answer) Dividing Decimals Move the decimal to the right on both numbers until there is nothing to the right of the decimal Dividing Decimals Video numerator the top number in a fraction denominator The bottom number in a fraction mixed number a number made up of a whole number AND a fraction 2 1/3 is a mixed number 7/3 is an improper fraction convert mixed number to improper fraction 2 1/4 = 9/4
