If you've ever tried to solve mathematical problems without any idea how to go about it, this book is for you.It will improve your ability to solve all kinds of mathematical problems whether in mathematics, science, engineering, business, or purely recreational mathematical problems (puzzles, games, etc.).
Pick variables to stand for the unknows, clearly labelling these variables with what they stand for. You need to do this for two reasons: " stands for, so you have to do the whole problem over again.
I did this on a calculus test — thank heavens it was a short test! (Technically, the "greater than" construction, in "Addition", is also backwards in the math from the English.
You'll be expected to know that a "dozen" is twelve; you may be expected to know that a "score" is twenty.
You'll be expected to know the number of days in a year, the number of hours in a day, and other basic units of measure.
But figuring out the actual equation can seem nearly impossible. Be advised, however: To learn "how to do" word problems, you will need to practice, practice, practice.
The first step to effectively translating and solving word problems is to read the problem entirely.
For instance, suppose you're told that "Shelby worked eight hours MTTh F and six hours WSat".
You would be expected to understand that this meant that she worked eight hours for each of the four days Monday, Tuesday, Thursday, and Friday; and six hours for each of the two days Wednesday and Saturday.
Carefully and clearly written, this indispensable guide will help students in every discipline avoid countless hours of frustration and wasted effort.
It is an ideal book for early undergraduate courses in mathematics, physical science, engineering, computer science, economics and other fields that require problem solving.
