Document Summary

We use numbers to count, quantify, and compute. Natural numbers include the number 0 and all the numbers obtained by counting up by. Integers include natural numbers and their negative counterparts (e. g. -14, 9, 10, -56) Rational numbers are either integers or numbers that can be expressed quotients of two integers (e. g. 12, , 4/5, 9/4, -2/3) Real numbers the natural, integer, and rational categories as well as numbers that cannot be expressed as a quotient of two integers (irrational) (e. g. 2, -4, -1/4, -1. 3, 4. 005) The number 531 can be written as the following sum: * the number 531 is expressed in base 10 because the terms involve the powers of 10. The position of the digits 1, 3, 5 is associated with the powers 0, 1 and 2 of 10 respectively. Decimal numbers are represented using 10 digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9).
