Whole Number - a number without fractions; no negitives Integer - can be either a positive number, a negative number, or zero Rational Number - can be expressed as a fraction Real Number - any number that can be placed on the number line, whether that be negative or positive, fraction or decimal GCF - Greatest Common Factor. The largest number that can divide each number from a set of numbers without a remainder. Ex. The G.C.F. of 8 and 12 is 4. prime factorization - Breaking down a composite number until all of the factors are prime Factors - Numbers that are multiplied together to get a product interval notation - A notation for describing an interval on a number line. The interval's endpoint(s) are given, and a parenthesis or bracket is used to indicate whether each endpoint is included in the interval. Prime Numbers - 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 Celsius to Fahrenheit - F=C×9/5+32 Fahrenheit to Celsius - C=(F−32)×5/9least common multiple - The smallest multiple (other than zero) that two or more numbers have in common. Table spoon to Ounce - 1 Tbs = .5 oz teaspoon to table spoon - 3 tbs = 1 Tbs Ounce to cup - 8 oz = 1c Tablespoon in a cup - 16 Liter to Gallon - 1 Liter = 0.264172 Gallons Coefficient - number in front of a variable Degree - highest exponent on a Variable Linear Equation - an equation whose graph is a straight line(all vars have a 1 exponent) Principal of Equality - Everything you do on one side of the = you do the same on the other. Slope - M = rise/run = (y2 - y1) / (x2 = x1) slope-intercept form - y=mx+b, where m is the slope and b is the y-intercept of the line. Point Slope form - y-y1=m(x-x1)Linear Inequalities - When you multiply or divide by a negative you switch the direction of the sign. quantitative variable - takes numerical values for which arithmetic operations such as adding and averaging make sense Categorical Variables - Data that can be placed in a category but can not be calculated directly Mean - average
