# SAT Math

 Integers Positive and negative whole numbers, and zero. NOT fractions or decimals Prime Number An integer that has exactly two distinct factors: Itself and 1. All prime numbers are positiv; the smallest prime number is 2.One is not a prime! Rational Numbers rationale Zahlene.g. (1/3); 2; -3 ... (not: e, pi, square 2) Irrational Numbers Not rational! Does not repeat, has no end.e.g.: e, pi, square(2) Real Numbers All numbers, except imaginary numbers Imaginarz Numbers e.g.: square(-1) Consecutive Numbers The members of a set listed in order, without skipping any.Consecutive Numbers: -3, -2, -1, 0, 1, 2...Consecutive positive multiples of 3: 3,6,9,12,... Distinct Numbers Numbers that are different from each other Sum + Difference - Product x Quotient / Remainder The integer left over after dividing, two numbers. e.g. 17/2, remainder is 1.Remember: on the Math Subject Test, a remainder is ALWAYS an integer!!! Reciprocal "Kehrwert" Positive Difference smaller - bigger number. Absolute Value "Betrag" Arithmetic Mean average Median Median Mode The value that occurs most often in a list. If no value appears more often than all the others in a list, then that has no mode. Factors Factors of an integer, are all the integers that can divide the integer.factors are smaller then the number itself Prime Factors e.g.8= 2*2*275= 5*5*3 Multiples The multiples of a number are all the numbers that are evenly divisible by your original number.smallest multiple of a is a!"postive integer multiples of 6" = 1 x 6, 2 x 6, 3 x 6, ...
