what is the use of maths in life?

Question

apart from addition subtraction,division and multiplication.what is the use of maths? where we are going to use algebra ,geometry,Pythagoras theorem etc?what is its use?please justify your answer?

Answer 1

Mathematics usually is good for someone who is going to be an accountant, or someone who is an into construction..or even if you want to be a teller at a bank or a cashier at a restaurant..Math is everywhere..Paying your rent or mortgage is dealing with math.

Answer 2

Some of mathematics, particularly the more advanced topics, is actually useless to the layperson; but a considerable part is useful.

Financial math (percentage, interest) is used all the time, when buying with a credit card, financing, mortgage, etc.

Basic geometry is used in construction. How do you assure that a wall is straight? How much tiling, paint, etc, do you need for a room, given its dimensions?

Probability is used in games of chance, like craps and poker. Do you know why a straight pays more than a pair?

Statistics is used, misused, and abused in everyday life: election polls, opinion polls, research results.

Algebra is great for abstracting classes of problems which differ only by the values involved. For example, many problems in everyday life reduce to 1st degree equations on one variable, but this is obvious only if you know 1st degree equations.

About more specialized topics:

Calculus is used, among many other uses, in construction. What is the minimal amount of steel needed to support a 80-story skyscraper, and still meeting the security requirements?

Differential equations have too many uses to count. More at the sources.

Answer 3

If nothing else, knowing math helps protect you from being cheated. For example, if you want to carpet a room, you can determine the amount of carpeting you will require to determine if the quote you received in correct. Not all rooms are perfect squares or rectangles, so some knowledge about geometry comes in handy. You can also use math in cooking if you need to double a recipe (or half it, for that matter). I have used both geometry (both plane and solid) and algebra to solve everyday problems, but I have to admit that I never used either trigonometry or calculus after I finished the classes. Learning enough math while you are young will also help you stay ahead of your kids once they start school. Algebra and pre-algebra problems are getting into the lower grades.

Answer 4

Let's see.

Simple algebra is used ALL the time. Any time you're planning anything financial -- a budget, an investment, etc. -- it turns out you're doing algebra. Ditto any other kind of plan or budget that you quantify, e.g. when managing your time.

Understanding probability/statistics is crucial to making informed decisions about public policy/voting, insurance, and a whole lot of risks to your life (e.g., which fun activities are too dangerous to do). Algebra is essential to using probability at all. If your need is a little more sophisticated -- well, prob/stats is disguised calculus, so you need at least precalculus to really understand them well.

If you want any kind of engineering/technical career, many kinds of math are crucial. If you don't, and you still want to make decent money in life, you should aspire to be in sales, marketing, or general business. So you need to understand financial planning.

Basically, if you want to live better than the folks in trailer parks, learn some math.

EDIT: All that said -- some of the more sophisticated factoring and so on aren't really used, and a lot of geometry and trig are pretty useless except to pave the way for calculus. Calculus is the real payoff. You can't really understand any science -- natural or social -- without it.

Answer 5

Algebra - I USE ALL THE TIME, in my geochemistry class for all types of geochemical problems.

Geometry - Extensively used in all engineering courses and many many many others. Real world application: Building anything & everything!!

Pythags Theorem. How about finding the radius of the earth given phi, & little 'r'.

Most subjects, especially sciences in general would not exist without the power of mathematics, Our society would be useless. & YOU wouldn't beable to sit around the house & watch tv. Because power lines are put up with the power of electrical engineering. We would be living in candle light, with wood-stoves.

Fun......

Math is like super - important, don't ever let anyone convince you that it isn't.

Answer 6

I've wondered this many times myself. If you're going to be an engineer or a scientist, you're obviously going to use higher levels of math. But if your profession of choice is, for example, an elementary school teacher or a manager of a store, you probably won't be using anything more than basic algebra. The reason that we are taught this seemingly useless math is a) to expand our knowledge of the world around us and b) to introduce us to possible careers.

Answer 7

Hi. I made a living out of a good understanding of Pythagoras's theorem. Programmed robots to inspect aircraft engine components. That and an understanding of geometry served me very well.

Answer 8

Well.. you can use math in many ways. Think about construction and architecture! These people need to have an understanding in geometry in order to make construction plans and blue prints as accurate as possible.

I also believe that trigonometry is quite important in game designing, when having different things shoot at different angles... at least I know this is true for many types of games made with macromedia flash.

Answer 9

maths is used all the time. when you are figuring out which is a better deal when purchasing items you are using algebra, when playing pool you are using trig, reading maps is like a geometry problem. also for people who make math a profession you can figure out how fast a car was going before crashing (if in an accident), actuaries use extensive math for risk assesment, financial investors use math to make wise decisions with your money. it is just at some point you use it and it comes easier and you don't have to always explain why you got your answer.

Answer 10

The use of math is so when you go to the store nobody will cheat you out of your money. That is very important to people. If you did not know how to do math then you won't have any money at all.
