Only got 5/10 right :D

[Mr Bean]

Got 7/10. I really didn't understand some of the questions:rotflmao:

I believe Pi rules is to take this test next school term:D

That wasn't bad at all.

How did you guess? ;) I just got my AP test results back and I passed out of Calc 1 & 2 for college. :)

[PurestLight]

I got 7/10 too. didnt understand :

If .4 < x < 1/2, x could equal ..... or

What's the value of (10-5)^2 + 12/4?

Think Ill stick to the http://bestsmileys.com/cleaning/12.gif and the http://bestsmileys.com/cleaning/1.gif

[Pi rules]

If .4 < x < 1/2, x could equal ..... or Highlight: convert .4 to percent and 1/2 to percent. Which answer (if any) is between those two percents?

What's the value of (10-5)^2 + 12/4? Highlight: do the math inside of parenthesis first, this: ^ means to the x power (2 in this case) so (10-5) times (10-5), then add 12/4, which isn't as complex as it looks.

[Nick Grana]

If .4 < x < 1/2, x could equal ..... or
What's the value of (10-5)^2 + 12/4?
If .4 is less than x and x is less than 1/2, x could equal 45.
10-5=5^2=25+(12/4=3)=28:cool:

[DELTREE]

The strange thing is: starting in first grade in MOST public schools, they give them a CALCULATOR; take that away from them and they are LOST!:sad:

[PurestLight]

Thanks for the answers :) It was the little symbols that threw me; I kind of thought ^ was 'to the power of' but I was none the wiser. And I didnt get the < in the context of the question. Now I get it. Sort of :D

What I don't understand is how 8/10 can be an A+. When did they change the grading? When I was in school 8/10 was barely a B.

I know way too many people completely dependent on a calculator. I should probably try to use it less as well. I love to program on it, though. :)

[Nick Grana]

Calculators should be banned until one understands how to do it long hand.
When you can long-hand cube roots, sine, cosine, and tangents, among other basic math skills, then you can use a calculator.
I love to program on it, though.
Easy. Try programming a slide rule.:D
Remember buying my first $100 calculator that could not only +.-. X, and /,
but could do percentage, exponential exponents, reciprocal, and square root.
Wow!!!:thrilled:

Can you even find a slide rule any more? I haven't seen any in years and years (not counting my Steven's wheel that is :cool: )

Seemingly easy.

[Moegopher]

I passed 8th grade math in school. Why might I want to do it again? Hehe.

[Nick Grana]

How many people actually use those kinds of questions in every day life.
I used to be in Calibration of DC and low frequency testing equipment, microwave testing equipment, and physical weights and measures, all one level under the National Bureau of Standards and had many formulas to be done to determine accuracy of testing equipment.
Outside that, never used it in grocery stores as they put little labels on the rack as to cost per ounce to compare easily.:happy:
No more....if 16oz is $1.98 and 15oz is $1.88, which is better deal?:D

Bleh... my calculator is $160, does symbolic calculous, differential and 3d graphs, and has the options for a "windows" interface...

[oracle128]

10/10. For the record, the TI-83 is the greatest calculator ever. I remember getting bored in class one day and making ASCII pong. Ah, good times...

[Nick Grana]

Have to remember, folks, that my TI was bought in the '60's. Every added function was a big deal and expensive.:happy:

[mmherk]

I am learning disabled in math...it is evil to me. :rotflmao:

[Moegopher]

I have one of the TI-84 Plus Silver Ed.. But I don't wanna cheat.

[Vercades]

4/10 here w/no calculator. I used to know how to figure fractions in my head eh, I'm a little rusty.

second time around 5/10 lol a prime integer... this quiz is really deceptive.

7/10 the third time around. Lol, it's all coming back to me now.

[Nick Grana]

Lol, it's all coming back to me now.
Hence, the saying: You don't use it, you lose it.

[PurestLight]

I didnt use a calculator, I got 7/10 and I bet I left school before you vercades :p

[Vercades]

I guess I'm just dumb or, my math teacher hated me.

[PurestLight]

I guess its down to what you were taught at school. Im revisiting this stuff because my kids show me their homework. I find it very difficult. I have always maintained that I cant do long division, but one of the kids had a problem and needed help and now I can do long division because I had to get my head round it. I think Im lazy. ps my maths teacher DID hate me lol

[smurfy]

Did anyone time themselves?
2 Mins 43 Seconds.

Result 10/10.

[dammit]

I can understand sorta why kids need to do it the hard way (like I had to) but don't really understand it as well. When I was a kid there was NO other way. Why dig a hole with a spade when you have a JCB??

[PurestLight]

http://www.fonefunshop.co.uk/forum/images/smilies/CAZex.gifwell Smurfy youre just a right clever dick arent you :p I think it took me at least 10 minutes :sad:

I think calculators shd be discouraged until the 'sum' can be done mentally. unless its one of those cosine/tangent things that are seriously not understandable (by me)

[dammit]

I used to think that way... only because I hate the kids these days for having calculators. At the end of the day.. why not use em?
Also googling for homework must be a bonus.
I HATE KIDS!!!!!

That's mature....

Cheers mate :D

[Vercades]

Mathematics isn't really a thing you can do well if you're not interested in it. I passed up to pre-calc and, struggled all the time. No one in my family knew it well enough so, I was on my own for the most part.

No one can know everything, you can only be a master of one thing as far as I'm concerned.

the ^ symbol wasn't used in my school days either. We just put a small (#) outside the number and the variable. It's look like this 4+x(#) instead of (4+x)^

What seperates alot of people in math is those that just remember the answers and apply them to the questions and, those that actually problem solve. That's the whole point of math to make you problem solve.

[Vercades]

Did anyone time themselves?
2 Mins 43 Seconds.

Result 10/10.
4-6 mins for me
and a 4/10 lol

If we disallow calculators, why not disallow computers?
Hey, look at those woodwork students using a beltsander, give 'em a sheet of sandpaper and a block of wood like I had to use.
Look at those sewing students using a sewing machine, give 'em a needle and thread and maybe a thimble ;) .
Let's take the microscopes away from the biology students while we're at it.

A calculator is just a tool like any other. When they go out into the real world, they'll be allowed to use a calculator won't they?

[Nick Grana]

You don't play well with other 4 year olds?:rotflmao:
Rudimentary math should be accomplished before using calculators.
Use your fingers or calculator on this simple problem:
2+6/2-2X2=?
If your answer isn't 1, then think (hint) hierarchy.:D

Exactly - you have to know the theory to get the right result from a calculator or your fingers or a pencil and paper.
If you don't understand what part of the calculation to process first your answer will be wrong no matter what tool you use.

[Vercades]

Or right, our teacher here discovered that if you factor an imaginary number in an equation, (I forget which) you'll skip tons of trial and error resulting with the right answer. She won some awards for it.

The variable is "i" in most of the equations.

http://mathforum.org/dr.math/faq/faq.imag.num.html

[Vercades]

dbl

[Nick Grana]

Your teacher may have used 'i' but I used to be heavy in formulas using imaginary numbers called 'J' factors.

As smurfy pointed out in my little math problem, no calculator or fingers and toes will solve a problem if the hierarchy is not known. That is why calculators should not be used until the basics are met.
Like the constipated mathematician that worked it out with a pencil, it has to be done.:D

[oracle128]

'i' and 'j' are both acceptable for representing imaginary numbers. In both cases, they need to be lowercase though.
As smurfy pointed out in my little math problem, no calculator or fingers and toes will solve a problem if the hierarchy is not known.In case you forgot the term, you're talking about BODMAS (http://www.easymaths.com/What_on_earth_is_Bodmas.htm).

Sadly... thats not true anymore. Any graphing calculator knows order of operations.

Orracle, in modern mathmatics j isn't acceptible for imaginary numbers anymore. i has to be used, but they've tried to elminate j since i, j, k are used for identity vectors in vectoc mechnics and vector fields.

[Vercades]

Yeah, that's what she called it. It wouldn't surprise me if she even wrote that webpage sounds like here.

[PurestLight]

Who decided BODMAS.

[PurestLight]

That was shorter than I intended lol but its probably just as well. I clicked enter early I think.

Who decides where the brackets go and why are they right? why cant the answer be 17 and not 25. If brackets hadnt been invented then the answer would be 25. If you set the question and therefore know the answer already, I suppose you can arrange the numbers however you like

hmmm :confused:

[Vercades]

Speculation doesn't do well in math, I learned that the hard way. :(

[PurestLight]

You are more than likely right. I guess I asked a non-question there. BODMAS will just have to continue being an enduring enigma for me :)

[Nick Grana]

Basic math requires one to multiply and divide before adding and subtracting.
Then it gets a little more complicated with brackets and sub brackets.
If one does not know these simple things, how on earth can one be expected to use them properly.

Here's the breakdown:

To clarify this question, mathematics has developed the following hierarchy of computations called order of operations:

Perform all operations that appear in grouping symbols first. If grouping symbols are nested, do the innermost first.

Raise all bases to powers in the order encountered moving from left to right.

Perform all multiplications/divisions in the order encountered moving from left to right.

Perform all additions/subtractions in the order encountered moving from left to right.

Here grouping symbols means parentheses ( ), brackets [ ], braces { }, etc. An example of a nested expression is (6 + 2 × (4 + 1)) ¸ 8. The innermost grouping symbol is (4+1) so the result is

(6 + 2 × (4 + 1)) ¸ 8 = (6 + 2 × 5) ¸ 8
= (6 + 10) ¸ 8
= 16 ¸ 8
= 2

Raising a base to a power (also known as an exponent) means repeated multiplication as in:

6³ = 6 × 6 × 6 = 216

If there's confusion with imaginary numbers and the unknown length of the 3-dimentional vector axes (i,j and k), why get rid of j but not i? :confused:

All I know is, I was taught to use 'i' in high school, but 'j' in uni. To me, it'd make more sense to just use x,y and z for 3D vector maths (the lower case, not to be confused with the actual axes, X,Y and Z).

Y'all be happy to know that I have passed math for my college class...got a ''B'' and graduated. I can be considered ''dyslexic'' when it comes to math...for I am learning disabled in it.

BTW...I am the proud owner of an Associates of Applied Sciences degree in Computer Networking Technology! w00t!

People will tell you it's not as good as a proper Degree, but don't listen to them.

Good job! :wave:
the Australian equivalent of an Associate's Degree
I was wondering that what an "Advanced Diploma" was.

i,j and k
I used these in Calculus, but as index variables in my calculator programs. ;)

i is like alpha in physics... used more than a $2 *****...

x,y,z aren't used for identity vectors because people would just be confused... although, since i,j,k are actually i hat, j hat, and k hat... I suppose the same could work for x,y and z... but hey... we don't control mathematics... we just get the headaches.

hmmm :confused:
Sorry, I'm going too far back in the topic, but I found this question VERY interesting...

Order of operations has been around for a very long time. It was obviously created to prevent people from getting different answers to the same question. No one person has really been given credit for it, it was more of a natural move in mathematics to avoid confusion.

The REALLY interesting thing about orders of operation is how beautifully it fit into a context-free grammar (see the Chomsky Hierarchy (http://en.wikipedia.org/wiki/Chomsky_hierarchy)) for computer language processing. It really showed how logical and appropriate the order of operations really is.

[Nick Grana]

Earliest Uses of Symbols of Operation and Grouping (http://www.veling.nl/anne/templars/operation.html):cool:

[Nick Grana]

Who decides where the brackets go and why are they right?
Julie, if you haven't already made the answer, just remember BODMAS is just an acronym for Order of Operation.
As in my simple example, 2+6/2-2X2=?, one has to just insert parenthesis, brackets, or braces in the right place(order).
2+6/2-2X2=? becomes 2+(6/2)-(2X2)=? becomes 2+3-4=1
As I stated earlier, you don't use it, you lose it. But a little practice like helping a child with their math homework brings it back quite quickly.
The majority of people do not need skills as this every day. Even grocery stores make it easier by noting cost per X on little tags so you don't have to calculate. I still do it in case they made a mistake.:D

[PurestLight]

Oh, I have Nick, thank you. You explained it extremely well. As you said, its not something you need to use everyday, but it doesnt come naturally to me and that is what I find irritating. Makes me feel a bit dim. Thats why I didnt reply, all the replies I nearly made sounded a bit 'blonde' :D Annoying thing is, I love maths and numbers. I dont remember a big deal being made of being taught BODMAS at school. My maths teacher when I was 14 / 15 was a real scary Mary and I didnt learn much from her at all
