Ask Dr. Math: Selected Answers to Common Questions


To make browsing easier for common questions, we have collected their answers and organized them under these topics:

  • About Mathematics
  • Algebra
  • Arithmetic
  • Calculators and Computers
  • Calculus
  • Discrete Mathematics
  • Factoring Numbers
  • Fractions, Decimals, Percentages
  • Functions
  • Geometry
  • Measurement
  • Number Sense/Number Theory
  • Place Value, Exponents
  • Probability/Statistics
  • Ratio/Proportion
  • Puzzles

Dr. Math Books


Dr. Math also makes house calls. We have published four books, two on geometry and two on algebra, which follow the topics of traditional courses but are composed entirely of actual questions and answers from the archives.

The material is presented in a much more conversational and informal tone than standard text books. Many teachers have found that having a copy as a classroom resource is a great aid, and we've also had a lot of parents tell us that the book is a big help to them when their son or daughter has homework questions.

Read reviews of our books by Maria Miller from HomeschoolMath.net. Also read Hema Gopalakrishnan's review of Dr. Math Gets You Ready for Algebra on the Mathematical Association of America (MAA) site.

Precalculus Tutorial


John W. Bales, in collaboration with the Department of Chemistry at Tuskegee University and the Department of Mathematics and Statistics at Georgia State University, have designed this tutorial for students enrolled in a precalculus, college algebra, or trigonometry course.

Bates explains, "It does not, and cannot, replace the textbook or other class resources or assignments. At the instructor's discretion, all or part of this tutorial may be assigned to students requesting supplemental resources or to the class at large."

  • Pretest
  • Functions and Graphs
  • Polynomial and Rational Functions
  • Exponential and Logarithmic Functions
  • Trigonometric Functions
  • Trigonometric Identities
  • Applications of Trigonometry
  • Systems of Equations
  • Sequences and Series
  • Conic Sections
  • Other online precalculus material

Math and Voting


The American Mathematical Society, the American Statistical Association, the Mathematical Association of America, and the Society for Industrial and Applied Mathematics recently announced that the theme for Mathematics Awareness Month, April, 2008, is Math and Voting.
