It seems that this is a fairly basic knowledge in high school math program, but there are still many people who are confused with this clause. Some people still think that the answer of 0 calculation by 0 has zero result, others think the answer will be 1. Of course, for those who master algebra, they have another answer .

According to mathematicians, whenever the number is divided by 0, the operation cannot be determined. Conversely, if 0 is a divided number, it can be divided by every other number, and the result is 0. But at the same time, the number 0 cannot be divided by itself.

Example: operation 0. a = 0 with any number a, we cannot find the number a by the reverse operation 0 divided by 0. But another reversal operation is 0: a = 0, it is always possible for all numbers a.

If you try to perform this operation on a handheld computer, a calculator on a smartphone and a computer, the device will report an error or cannot perform the calculation.
