The Actual Fermat-Pascal Correspondence

If you are a lover of the history of mathematics, then I am sure that you will be fermat-pascal correspondenceinterested to read the translation of the actual Fermat-Pascal correspondence. In the letters the two mathematicians discussed solutions to gambling problems. These discussions eventually led to understanding of the modern concepts of probability.

Blaise Pascal was a known mathematician, physicist, philospher and inventor in his time. He was also famous for inventing the pascal’s calculator, the first mechanical calculator that could perform automatic addition, subtraction, multiplication and division.  Pierre Fermat, on the other hand, was an amateur mathematician (he was a lawyer by profession) who made significant contributions in number theory, analytic geometry,  and probability. One of his famous conjectures was the Fermat’s Last Theorem

Book Review: How to Solve Word Problems in Algebra

How to Solve Word Problems in Algebra: A Solved Problems Approach is a   book ideal for middle school and high school students who want to learn about solving word problems. The book offers step-by-step method in solving different types of word  problems.

The topics covered in this book are number, motion (time, rate, distance), mixtures, coins, age, lever, finance, work, digit, and problems on geometric figures. It also contains problems on quadratics and problems involving two unknowns. In addition, each chapter has worked examples and at least 10 supplementary problems with solutions.

Since the book teaches problem solving step by step, it can be a good supplementary material or self-study guide for students.
