In This Chapter
Understanding the basics of formulas and their properties
Converting and managing units in formulas
Turning formulas you know into other helpful formulas
The word formula has a special meaning in mathematics, but it's also everywhere in pop culture. It can mean many things, but all the uses of the word come from the same idea: It's method of doing something that should produce the same result every time. In mathematics, a formula is a compact rule for getting something done mathematically. It's the math equivalent of "Never run with scissors" or "Always say please and thank you." It always works.
What's important to you is that, no matter what career you're in, you use formulas to speed up math. You can use off-the-shelf formulas (and we offer many in this book), but from time to time you make your own. And your own custom formulas make your work go even better because they apply directly to what you're doing.
In this chapter, you get the formula for working with formulas. You discover what the parts of a formula are and what alterations you can make to its structure by moving parts around. You also work with units in formulas and whip up your own home-brewed formulas.
