As a mathematical expert, I'm here to clarify a common misconception regarding division by zero. The concept of infinity is a fascinating one in mathematics, and it's important to distinguish between the idea of infinity and actual numbers. Infinity is not a number; it's a concept that represents an unbounded quantity that is larger than any finite number. It's used to describe things that are limitless or extend indefinitely.
When we talk about division, we're referring to the process of determining how many times a number, the divisor, fits into another number, the dividend. For example, when you divide 6 by 3, you're asking how many times 3 goes into 6. The answer is 2 because 2 times 3 equals 6. This is a straightforward case where the division is well-defined and yields a finite result.
However, when it comes to dividing by zero, the situation changes dramatically. The operation of division by zero does not yield a finite number, nor does it yield infinity. Instead, it is considered undefined. Here's why:
1. Multiplicative Inverse: In mathematics, every non-zero number has a multiplicative inverse, which is a number that, when multiplied by the original number, yields 1. For example, the inverse of 2 is 1/2 because 2 * (1/2) = 1. However, zero does not have a multiplicative inverse because there is no number that you can multiply by zero to get 1. If there were such a number, let's call it x, then 0 * x = 1, which is a contradiction because anything multiplied by zero is zero.
2. Consistency of Arithmetic Operations: Arithmetic operations must be consistent. If dividing by zero were to yield a number (finite or infinite), it would violate the consistency of arithmetic. For instance, consider the equation x * 0 = y. If we were to divide both sides by zero to "solve" for x, we would get x = y/0, which would imply that any number could be the solution, leading to an inconsistency.
3. Limit Concept: When approaching zero from the positive side, division by a positive number gets larger and larger (approaches positive infinity), and when approaching zero from the negative side, it gets smaller and smaller (approaches negative infinity). As you get infinitely close to zero, the result of the division does not stabilize to a finite number or infinity; it becomes undefined.
4. Logical Contradictions: If we were to accept division by zero as yielding infinity, it would lead to logical contradictions. For example, if 1/0 were infinity, then multiplying both sides of the equation by 0 should give 0 = infinity * 0, which is not true since 0 times any number is 0.
In summary, dividing by zero is undefined because it does not correspond to any real number, it violates the principles of arithmetic, and it leads to logical inconsistencies. The concept of infinity is a separate matter and should not be confused with the result of a division operation.

Instead of just assigning one willy nilly, we say that infinity isn't a number, and that 1/0 is undefined. When something is divided by 0, why is the answer undefined? The reason is related to the associated multiplication question. If you divide 6 by 3 the answer is 2 because 2 times 3 IS 6.
