Something in philosophy of mathematics;

During history mathematicians decided the -1/1 is equal to 1/-1.

Devision makes them both -1.

But maybe there is a catch here. What do I mean ?

The result minus one actually says it is allowed to devide bigger number in smaller number and that the result of this Devision equals the devision of smaller number by bigger number,

say for example 2/3 equals 3/2. Is that plausible? No.

So then why is it plausible for minus?

Here is my honest attempt..

case 1: -x/y : you are dividing a negative amount .. will always equal y amounts of negative quantities; Case 2: y/-x is hard, see its not true in reality that you can divide by a negative sum, nor is it logical. Im trying to get somewhere. 1 and -1 do have the same magnitude tho.. so your logic is off it would be false if you use -1/3 = 1/-2

my syntax is probably wrong since the examples -1/1 and 1/-1 are the same number, thus should be given the same variable so whatever you set x... yada

It gets complicated when you take the negative out of the fraction.. how the **** do you multiply something of quanity by a negative value?!

-1/1 and 1/-1 = -1( 1/1)

A minus (-) just represents a negation of a number when it is by itself. The minus is applied after the divison. In essence the minus is being applied to the in this fashion -(1/1) in both cases. Correct me if I am wrong

Lmfao! Where do you find these things??

The reason that 1/1 and -1/1 is that the absolute value /-1/ and /1/ are the same, the only difference is the sign.

right.. I said magnitude, and that case is different from -1/3 and 1/-2 thats why the poster's logic is wrong..

But, how does it follow that it is logical to multiply by a negative sum?

The first post doesnt make any sense, the only reason that you can swap the numerator and the denominator is because they are the same number only with different signs, essentially you are just swapping the negative sign, the same logic does not apply if they are different numbers

You can't divide by a negative number?
