# Talk:formula

is the pronounciation of the multiple of formula....formul-ii or formul-ee???

For definition #1, how does "equation" differ from "formula"? In grade school I was taught that a = b + c is an equation but b+c is a formula. Nowadays b+c is often called an expression, whereas a = b + c is often called both an equation and a formula.

- Umm, there's not a lot of difference, but from what I understand a "formula" is generally used for simple equations that are used to give one result from a set of values (the w:Quadratic formula etc.). An equation is more general and may not need any further information added to "solve" or may be solvable in many different ways depending on what information is available.

- An equation ALWAYS has an equal sign. A formula can be lots of different things - e.g. a receipe for how to make muffins, or the chemical formula for nitric acid. It can also be an equation. SemperBlotto 21:41, 2 May 2008 (UTC)
