Document Summary

At the end of this chapter you should be able to: Perform basic arithmetic operations and simplify algebraic expressions. Solve equations in one unknown, including equations involving fractions. Understand the meaning of no solution and infinitely many solutions. The numbers that is often used to count items: 1, 2, 3, 4, . Whole numbers without a decimal point: 0, +1, +2, +3, +4, . Positive integers: 1, 2, 3, 4, . Negative integers: 1, 2, 3, 4, . Numbers that can be expressed as a fraction of integers such as a / b (= a b), where both a and b are integers. Infinite decimal fractions (recurring or periodic): 1/3, 2/9, etc. Numbers that can not be expressed as a fraction of integers = nonrecurring infinite decimal fractions: Special values such as (pi), or e (exponential), etc. Adding: if all the signs are the same, simply add all the terms and give the answer with the common overall sign.
