Therefore, it is perfectly fine if you allow division by $0$, but then in order to make algebraic property "rich" enough to do mathematics your number system should only contain $0$ but nothing else. In fact, for integers, people do say that $0$ is divisible by $0$.
As x approaches zero from the left, y tends to negative infinity. In mathematics, division by zero, division where the divisor (denominator) is zero, is a unique and problematic special case. Using fraction notation, the general example can be written as , where is the dividend (numerator).
One Equals Zero! The following is a “proof” that one equals zero. Consider two non-zero numbers x and y such that. x = y. Then x 2 = xy. Subtract the same thing from both sides: x 2 – y 2 = xy – y 2 . Dividing by (x-y), obtain. x + y = y.
As much as we would like to have an answer for "what's 1 divided by 0?" it's sadly impossible to have an answer. The reason, in short, is that whatever we may answer, we will then have to agree that that answer times 0 equals to 1, and that cannot be true, because anything times 0 is 0.
10 Δεκ 2018 · What you’re saying here is that you can apply the reasoning used to prove that a/a = 1, namely that a^1/a^1 = a^{1-1} = a^0 = 1, to the case where a = 0. The problem is that this only shows that 1 is a possible value of 0/0.

Try Multiplying By Zero. So let us try using our new "numbers". For example, we know that zero times any number is zero: Example: 0×1 = 0, 0×2 = 0, etc. So that should also be true for 1 0: 0 × 1 0 = 0. But we could also rearrange it a little like this: 0 × 1 0 = 0 0 × 1 = 1. (Careful!
