My math teacher ALWAYS gets mad when we ask " When are we going to use algebra in real life?" but he never answers us, has any one here actually used algebra in real life?

Edit: ok i know that basic algebra is essential in the real world, and it's easy as hell but when am i ever going to use a liner equation? btw i never said it's hard, it all comes very easy to me, i just find the really advanced stuff useless.

Yes. You use it in a test. Said test, gets you your job.

tbh i would like what we learn in maths to have use in everyday life what i learnt in maths has basicly gone out of my head anyway because i only need to know the basic stuff

depends on what you want to do with your life.
im studying mechanical engineering in college so of course i use it all the time.
if youre doing anything in the science or engineering field then you use it very often believe it or not.

if you dont use algebra in real life then you probably have a dead end job that isnt worth doing.....or youre a pornstar
Get off this damn forum and play your damn guitar.

in geometry, calc, physics, stat and economics(in a lopsided kind of way) all of which are used a lot more than you'd think plus it's pretty much mandatory for college

Algebra is used for just about everything. Not to mention, it's easy, so I don't get why you're complaining.

That's not true. There are many fulfilling jobs which don't require algebra.

You don't.

They're excuse is, 'you're learning knowledge and applying it. Something very common in everyday life.'

Unless you actually are a mathematician, you will never need to use surds, circle theorems or the rest of it.

TS is fail, it teaches your mind to think in a certain way and its in your test fail the test then dont go to school

It also makes hundreds of other maths calculations easy, im in fast track math and im in year 9 at the moment and i got to tell im glad i know it

if you didnt do it you would likely complain about not being able to its just maths deal with it and grow up

You use letters to take the place of numbers which will vary depending on the situation to find a re-usable rule. It works.

ITT: Anti-algebra "rebels". It's all very cute.

I use algebra for geometric purposes all the time, and I'm not doing anything maths-related at work or at uni. Also for calculating what I have to make to keep a certain GPA, etc.

Jobs that require algebra include: accountant, marketing manager, business manager, chemist, biologist, middle school or high school math teacher, drafter, engineer, carpenter, some plumbing jobs, architect, dentist, doctor, pharmacist, nurse, geologist, financial planner, civil engineer, artillery gunner, and geographic information systems technician.

Well, most engineers have.


And even if you never use it again it'll have helped your brain.

This, although you never will use it in your job along with most upper level math courses (unless you are pursuing a career that uses math) it still helps you think in a more logical way and helps with problem solving.
#30
the alternative is you don't learn algebra and commit to your chosen career path (one which doesn't involve algebra) from the age of 13.

if you're confident that you know/knew what you want/ed to do at that age, good for you, switch off. otherwise, not teaching it to kids would be denying a ton of people the opportunity to choose a career in a field involving the use of algebra.

you use it all the time if your in any kind of math/science related field (physics, engineering, etc.). In fact, you use it so much, that you forget you're doing algebra. It becomes such a basic concept, that it just becomes "number crunching". Seriously, a lot of the problems I have in exams require a lot of algebraic manipulation of equations or concepts that I had to learn for the test. Something that comes up a lot is in mechanics of materials.

They give me a few bars with pulleys or gears with an unknown applied load (a torque for example). Sometimes they give me the deformation of the beams as well as the resulting stress in the beams due to torque (usually I get a table with ultimate yeild stresses and tensile stresses etc.). They want to know what is the minimum radius of the bar if I want to prevent failure. this requires me to apply the equations I know and algebraically solve backwards to get the radius.

While most of this stuff is already tabulated in books and journals and sometimes even done by computers, it helps to, in at least one point in your life, understand how it works.

only time iv used it really is this

assets=liability+capital


A=L+C

im doing accounts btw

Edit: what i think ts is getting on at is the hardcore algibra

like n1(4+n2)

i think algibra that turns into graphs was the worst like y=x would be a straight line going verticaly

then you would have mind **** ones that would make a line that looks like a sound wave

those letters are still numbers, and geometry and physics uses a shit load of algebra
if it we didn't have algebra or all the scientific developments it led to then we'd be living in a society equal to Europe in the 10th century if not worse

I remember when I was in Algebra, we had to say what we hope to learn in the class or something, and a redneck kid said something along the lines of "I ain't never gonna use no letters in my math" and my teacher just said "Well, he's right, you really don't use algebra in most careers".

Wow, great job turning off the whole class. Dumbass teacher. What if you want to fence in an area of your yard that isn't rectangular? Geometry + algebra == way less work for you.
