Why must we learn algerbra, trigonmetry and geometry?

Question

my grandma and i were just having a discussion about these subjects. i am going to school tommorow and i will be in algebra 1-2b. why must we learn this. will i ever have a home with a hectagon room? i understand that kids need to learn the basics such as addition, subtraction, multiplication and division. times tables, fractions percents. but why would we need to know y= 143x+6? i mean will i ever need to use this?

Answer 1

The formula for the slope of a line. Yes your gonna need it, if you wanna make more than minimum wage the rest of your life. Bite your teeth and grind through it. And be thankful it's not the 2nd order Rate Law!

Answer 2

Didn't they ever do any word problems, like "If you worked 143 hours in December and got paid $5 per hour plus a Christmas bonus of $6 how much would your paycheck be?" or "I have a living room that is 10 feet by 15 feet, what will carpeting at $10 per square yard cost me to redo that room?" Just because you haven't seen the use yet doesn't mean it has no purpose.

Answer 3

You need to get a broad based education so that you can find out what you like and are good at. Most of us never use most of the things we learn in school. I have never had some one on the street ask me to solve a quadratic equation or when Columbus discovered American or how to diagram a sentence. But I know what my strong areas are and what I am good at.

Answer 4

I was in your boat back in high school. I hated (still do) math. Algebra is good to know. Geometry/trig....pointless unless you are going to college after school, and more importantly if you'll be going into a science/math field of employement. But, to tell the truth....I've never used anything I learned in geometry in 'real life'. So, memorize for your assignments/tests and feel free to forget it all ;)

Answer 5

Good question. Because of the career I chose, I didn't need any of the higher mathematics. However, I am grateful that I endured and sometimes willingly participated in this structured discipline. If nothing else, it helps to recognize that stretching the brain is not a bad thing. Good luck to you.

Answer 6

you might not have a hectagon room but rest assured that all your rooms will not be perfect squares.
You will use this info more than you know and if you never do again it helps your mind to expand in ways other than the norm. It helps your creative side take over since you have to actually think about the answer and not just memorize them.

Answer 7

Because some people will use it. School is supposed to give you a taste of everything. What will your career be in the future? Are you preparing for college, which uses advanced math? Don't think of it as a matter of "will I use this." Think of it as...this is asked of me, and so I will do it to get the grades I need for a prosperous future. Besides...if you gain as much knowlege as you can, now, maybe someday you will use it. Who knows what you may need to do?

Answer 8

you'll use algebra all your life. it's a way of problem solving when you need to predict things. you'll see...
trigonometry and calculus are not used much in everyday life, but the opportunity to take those subjects in school gives kids a chance to check it out and see if they might like a career that involves those skills - engineering, research, etc.
free public education in America is a huge gift and opportunity - I hope you enjoy all of it you can!

Answer 9

I suck at math but every now and then I've found a use for algebra or geometry (well, the part about proofs and logic anyway). I still have to find a practical use for trigonometry in my life.

Answer 10

If you want to become a teacher, account, architect, designer for computors,
a cosmotagist, doctor, engineer. Just about everything that lets you make hundred thousands in life. Unless you want to work as at a gas station, its pretty important. Plus just knowing this stuff gets you into college!!
