0. the number of mystery and emptyness

Sorry, I see a lot of topics relating to 0. I want to collect most of those ideas here.
So what can we say or know about 0? If we have 0 groups of a number, than we have 0. If we add or take away 0 units, we do not change the unit total. 0 is less than any positive decimal number to exist, even to infinity. 0 is in such a way "void" that it can get rid of terms in equations when multiplied. It's sign is not even positive or negative.

So how can you solve xy = 0? is there no solution or 3 solutions? 3 solutions would be based on Boolean theory: x OR y would have to be 0. But there is no way to know.

Here's my input on division by 0:

1/0

This is read as the number 1 split into groups of 0, there is a possibility of infinite amount of 0s added or subtracted to 1 but still an undefined amount. I know that no matter how many 0s we add or subtract, there will never be a change in the negative side or the positive side or the actual number. Because 0 is neutral, it has no sign. So when we multiply by 0 (the "void"), we have to think that when we multiply by the same signs, I expect groups of negative and positive numbers in a positive answer. But different signs give a negative answer. I guess multiplying with a number that is not negative or positive just makes it neutral. And the only number without a sign is 0.

So I'm thinking in terms of signs when it comes to dividing by 0. If 0 had a sign, we could divide by positive 0 and get a number in a range of 0 to positive infinity or "-0" would be 0 to negative infinity. But since 0 has no sign, theory complains and says "I don't know whether 0 is positive or negative, and I don't even know how many 0s actually do exist in the number if not infinitely". x/0 has been proven undefined because of that.

I would like as much input on this as I can get!

Re: 0. the number of mystery and emptyness

the solution to xy = 0, is that there is no solution; only a partial solution that atleast one of x and y is 0, you can say nothing about both of them together.

Watch out, you can get π years in jail for dividing by zero.

Let me know if you think the poster called Megabrain is an idiot.
