Math Problem

Kaxbe, on 30 April 2011 - 12:56 AM, said:

The reason "÷" is used on calculators is because it is generally understood to be division. However, my point still stands. It is used only in basic math because it implies math between the two numbers directly beside it. For example:

18÷9÷2

What does this equal? It equals 1. Because in basic, elementary grade math when all the processes are of equal value according to any order of operations, it is done left to right.

Ok, how about this.
Kabe or migrant, answer these.

36÷18÷2=
36/18÷2=
36/18/2=

Smash, shut up. it is not trolling. We are not being trolled. We want to talk about this andd that is exactly what we are going to do.

First one is doable. The second one mixes division symbols, making it difficult to interpret. Third one is just terrible to write the way you wrote it.

The second one, by your arguments, can have only one answer.
The devision symbole puts everything on each side into one value before using it.
36÷18÷2=2
36/18÷2=4
36/18/2=Nothing you say? Do you mean that trying to use a fraction in here is a bad idea? Could it be that it does not work and that is that? Yes, yes it could.

Anouther way to interpret the / symbol in the way you have argued it is that it has the absolute lowest presedence. Everythinge on each side must be treated as a single value.

sort of like
() then squares and roots then *÷ then +- then /

It devides everything on one side by everything on anouther side. That means it happens last unless brackets/prenthesis say otherwise.

/ and * probably have the same precedence when used by most people in here.

Eg. a*b/c is (ab)/c but a/b*c is (a/b)c

...Which boils down partially to what the essence of the original problem was, but I'm not going to start on that again.

Kabe and migrant have been trying to argue a difference between / and ÷.
I don't really by it but there is always the possability they just know something that me and you do not so I am rolling with it until we find a point where it contradicts itself such as 36/18/2. I am stilll waiting for one of them to tell my why this is not disproof of the idea that a symbol for fractions is not the same as a symbol for devision between two terms.

If we could disprove the idea that the / symbol is used like they say it is, we would be done here.

Uh, NO. I'm trying to make this here clear:

Kaxbe, on 20 April 2011 - 07:19 PM, said:

the obelus is used to express division between only two terms.

And while I quote Kaxbe, he and I are saying two different things, craft. I just liked how he put these words together here. Kaxbe here is still stuck on the "left-to-right" error. I'm saying any ambiguous expression using the / or the ÷ symbols is flawed! Maths does not work left to right, never has, never will. You keep the signs and the operations right, you can do it in any order you like. Which is why any expression with three or more terms with an obelus sign is flawed (unless it is before the last term only and all other operations are multiplications).

3 * 9 / 13.5 = 2 Fair (but probably unadvisable)
3 / 13.5 * 9 = ERROR
13.5 + 13.5 / 9 = ERROR
13.5 / 9 + 13.5 = ERROR

Again:

Kaxbe, on 20 April 2011 - 07:19 PM, said:

the obelus is used to express division between only two terms.

Which means in any expression with more than 2 terms, you should be writting division as a FRACTION instead. I.e. using TWO lines (or more if required). When coming short of that, due to limited text editors not meant for maths, use brackets liberally, so that by the time you get to the division, there are only two terms left inside that bracket.

The obelus is more useful when doing long division (though the newer calculator-dependent generation probably doesn't even remember how to do it). In continental european countries, the ":" symbol is often used to describe division in this case. The english and their former colonies tend to use "÷", and the slash symbol for division I believe is a creation of computer science (though I might be wrong on this one)

Example said:

257 : 12 = 21.4166...
24
.17
.12
..50
..48
...20
...12
....80
....72
.....80
.....72
...

18÷9÷2 equals 1. Because in basic, elementary grade math when all the processes are of equal value according to any order of operations, it is done left to right.

And at this point, I agree. They are the same symbol and have the same presedence without argument and must be read from left to right.
18÷9÷2 = (18÷9)÷2=2÷2=1
so
36÷18÷2=(36÷18)÷2=2÷2=1

Aw fuck. Well, it does not = ERROR either so we were both wrong. Well, he was the intention.
36÷18÷2= 1
36/18÷2= 2
36/18/2= does not make any god danmed sence and kind of shows that the a symbole for fractions should never be used in horisontal math.

Also, that third part totaly ignored the idea that the / symbole is a fraction symbol. It treats it just like the ÷.
Of corse, if you wanted to express a fraction of the form
2+1x*+5y
2x
You could use the ÷ by stating
(2+1x*5y)÷(2x)
so the idea of a fraction symbol in horisontal math is superfluous.

It totally is.

Now you're saying that "/" could be a fraction sign OR a division operator. The problem, with an actual pencil and paper, you could just write a fraction like ¼ so there would be no issue with differentiating them.

Also, what does this have to do with the initial equation?

That's part of the issue. I don't. I am just trying to look at other peoples sides like I have the whole time. That is also why I said "Guess it's Kabe's turn again". He seems to be the person who has heard of the difference between the two before now.

Acctualy, you know what? According to kabe.
2/4/8 is
2
4
8
this it totaly a mathmatical error.
The usage of a horisontal fraction symbol is bullshit and the problem that this thread is about didn't use it anyway.
Regardless of what "/" is it has been shown earlyer that 48÷2*12 has to be the same as 48*.5*12 because 1-2+3 is the same as 1+(-2)+3 and not the same as 1-(2+3) because the subtraction symbol is actualy just a negative symbol that is implying addition and so subtraction is actualy the same operation as addition and could not possably have lower presedence. The answer was 288 regardless of the meaning of / and / should never ever be used in horisontal math to indecate a fraction. Arguments?

I think it can be used if you have people who are bright enough to assume it means division. And if it does mean a fraction, to have it either stated or for it to be turned into a decimal.

One is not bright because they assume the same things you do. One it bright because they understand what is actualy going on and/or because they can figure out why things are the way they are on there own.

Ninjaed. It is fourm speek that I picked up while I was on thie very fourm that appenrantly means that while you were editing your post someone else had already psoted on whatever you were going to talk about.
I think it is odd to but that's what I have seen it called.

Either way, / is just not good enough to be used as a fraction symbol. It is sub par.
If someon was to write

3     6
_  /  _
4     3

Then that might be one thing but as is, the symbol does not properly do its job.
If someone could go get a custom
¼
then that would be fine becuse those stack a bit and clearly show themeslfs as a single value but as it is "/" is not equiped to do it's job.

The difference between devision and fractions is null until you involve more then one term on each side.
The equation 2x+4y÷2y+x is not the same as the fraction
2x+4y
2y+x

That equation, in every one of the theorys we have used, is
2x+4y÷2y+x = 2x+2+x = 3x+2

2x+4y
