Are you bad at math?

Bennett, Jeffrey.  Math for Life: Crucial Ideas You Didn't Learn in School.  Updated Edition.  
        Boulder, CO: Big Kid Science, 2013.  ISBN: 978-1-937548-36-0

Do you consider yourself "bad" at math?  Did you do well in math while in school?  Well, it does not matter what answer you give to those questions as Jeffrey Bennett demonstrates in Math for Life.  You are using math in your daily life whether you realize it or not, although it is generally not algebraic equations.  Dividing a pie evenly, cutting a pizza to fit the number of folks around the table, baking with its use of proportions, etc. all these tasks have you using math unconsciously. 

What Jeffrey Bennett does is have you think about math outside the classroom.  The best chapters are the early ones ("Thinking with Numbers" and "Statistical Thinking")  which concentrate on your interaction with numbers in the real world (not the artificial world of the classroom).  Later chapters focus on money, taxes, deficit spending in the USA, energy, politics and growth.  These later chapters get more esoteric in their focus and reveal authorial bias (conscious and unconscious) in regard to the premise of the question asked or the answers he suggests as correct.

Overall, despite issues with regarding authorial leanings and suggestions in various chapters, Jeffery Bennett does provide sound advice in regard to the importance of math in everyday life and gives generally sound advice on how to improve.  Just remember to ignore advice with which you disagree.
