Mathematics in Context: Expressions and Formulas

Encycbrita, "Mathematics in Context: "
Holt McDougal | 2006 | ISBN: 0030396174 | 46 pages | PDF | 3 MB

Dear Student,
Welcome to Expressions and Formulas.
Imagine you are shopping for a new bike. How do you determine
the size frame that fits your body best? Bicycle manufacturers have a
formula that uses leg length to find the right size bike for each rider.
In this unit, you will use this formula as well as many others. You will
devise your own formulas by studying the data and processes in the
story. Then you will apply your own formula to solve new problems.
In this unit, you will also learn new forms of mathematical writing.
You will use arrow strings, arithmetic trees, and parentheses. These
new tools will help you interpret problems as well as apply formulas
to find problem solutions.
As you study this unit, look for additional formulas in your daily life
outside the mathematics classroom, such as the formula for sales tax
or cab rates. Formulas are all around us!
Sincerely,
The Mathematics in Context Development Team
