In mathematics and in the sciences, a formula (plural: formulae, formulæ or formulas) is a concise way of expressing information symbolically (as in a mathematical or chemical formula), or a general relationship between quantities. One of many famous formulae is Albert Einstein's E = mc² (see special relativity).

In mathematics, a formula is a key to solve an equation with variables. For example, the problem of determining the volume of a sphere is one that requires a significant amount of integral calculus to solve. However, having done this once, mathematicians can produce a formula to describe the volume in terms of some other parameter (the radius for example). This particular formula is:

Having determined this result, and having a sphere of which we know the radius we can quickly and easily determine the volume. Note that the quantities V, the volume, and r the radius are expressed as single letters. This convention, while less important in a relatively simple formula, means that mathematicians can more quickly manipulate larger and more complex formulae.

In general mathematical use there is no essential difference in meaning with the term "expression", although the word "formula" tends to be reserved for an expression that "can stand on its own", that has a meaning outside of the immediate context in which it appears and a significance that can be grasped intuitively.

The majority of all mathematical study revolves around formulae in many different forms from quadratic equations to the equations of motion (mainly used in mechanical mathematics and physics). In a general context, formulae are applied to provide a mathematical solution for real world problems. Some may be general formulae designed to explain a phenomenon experienced everywhere - an example is force = mass × acceleration. It is a formula which applies anywhere in the universe. Other formulae may be specially created to solve a particular problem - for example using the equation of a sine curve to model the movement of the tides in a bay. In all cases however, formulae form the basis for all calculations.

How much formula does your 5 month old drink?
Q. My 5 month old daughter has just started solids along with her formula. She drinks 3 6oz bottles during the day and a 7oz at bedtime. I also give her 1 container of stage 1 baby food and 2-3 tablespoons of cereal. I was just wondering how many ounces of formula your baby drinks at eat feeding and how do you know when to increase the amount of ounces per bottle? I'm a first time mom and have LOTS of questions! She is doing great with the solids, she would eat more if I would let her!

A. my daughter is going to be five months soon and is very similar...i think she maybe has a few more ounces than yours during the day but other than that they have very similar feeding amounts. your doing great mom!

What is enough formula to give a 3 month old?
Q. Hello, my daughter is 3 months old and I recently increased her formula intake from 4 to 6 oz every 3-4 hours. But ever since I've increased her formula intake she sleeps alot more. She used to stay up the majority of the day but now, after every feeding she falls asleep for 1-2 hours at a time. She's still sleeping through the night but I wanted to know if this is normal or if I should decrease her intake back to 4 oz. The reason I increased her intake is because she was still hungry after the 4 oz. Thank You.

A. Sounds normal to me. My son wanted about 5 ounces at every feeding at that age and cooked whole grain cereal twice a day in addition around 4 months. You'll find as they grow that their routines will shift around a little bit. It's OK.

what formula can i use in excel to calculate expenses based on the income of 2 people?
Q. If i make $3000 a month and my roommate $2000 i need to know how to calculate expenses based on both of our incomes without doing the 50/50 deal. I'd like to use excel. Does anyone have a template or at least the formula?
Asked by Juan A - Mon Jun 30 17:55:24 2008 - - 1 Answers - 0 Comments

A. Sure... if you would like to make it proportional to your incomes, just take 3000 / 5000 * each expense for your portion (5000 is the sum of your incomes monthly), and 2000 / 5000 * each expense for your roommate. Or, more simply, 60% for you and 40% for your roommate. In Excel you can use, if an expense were in cell A1: =3000/5000*A1 To get your portion, or =2000/5000*A1 for your roommate's. Does that help?
