Precalculus, 9th Edition

Review Some students in my precalculus class are very weak in algebra. . . . The 'Algebra Help' is definitely beneficial to students . . . [as are the] 'Warning/Cautions' which help those students avoid common mistakes that others make. [And] the 'Student Tips' really guide students in what they should recognize after an example is presented. . . . Larson's text is among the best precalculus books [I've found].""I am very satisfied with the exercises as well as the review exercises, they are helpful and there is a range of easy, medium, and hard problems. There is a wealth of example problems and I can easily find examples that show where common algebraic mistakes occur. . . . The use of different colored text makes them very easy to understand."
