What is zero? Is zero equal to zero? Answers: Zero is a number = nothing = nothingness. First Example: A person X earned $ 100, then he has the number 100. The same person X lost $ 100, Then the result is that: the person X has zero $, which means he has nothing. A second example: A person Y earned $ 500, hence he has the number 500. the same person Y lost the $500, therefore he has zero $, which also means he has nothing. Is the first nothing equal to the second nothing?? In my opinion, it is certainly NOT; because the first nothing or the first zero resulted from a calculation completely different from the second calculation. In other words, the first zero belongs to the space of nothingness and the second zero belongs to another space of nothingness and both spaces belong to the space of total universal nothingness. From here, we find that zero is not equal to zero in the physical cosmic universal sense but is equal in the numerical sense. Another example: Is 0 0 = 0 ? The answer is may be yes, but this is not always correct, because we have also 0 1 = 0, 0 2 = 0, ... despite that the numbers 0,1, 2 are different. Therefore, in all of the previous cases, we can not be sure which of the following is the correct answer:
0 0 0 = 0, = 1, = 2, ... which means that if zero equal to zero in absolute since, then the answer 0 0 0 0 0 would be = 1 , but we say that this quantity is undefined or that the limit of such quantity is 0 0 indeterminate, because it may be 0, 1, 2, and so on… Why, then, multiplying the number zero by any real number equal to zero? The answer is so simple. Assume that you have 10 dollars and you give one dollar to someone, it means that (one person multiplied by one dollar = one dollar) and if another person came to you and you gave him $ 2 it means that (one person multiplied by the number of $ 2 = $ 2). If a third person came to you and you gave him the reminder $ 7, that means that (one person multiplied by $ 7 = $ 7) and so you spent all your $ 10 and you have $ 0. On the contrary, if the first man came to you and you did not give him anything, that is 1 0 = 0 , and if you did not give the other two men anything that is 2 0 = 0 , then the result is that: you kept the ten dollars and we have proved the rule that "any real number multiplied by zero will be zero.
