What is infinity divided by half?

Published in Mathematics 2 mins read

Infinity divided by half is still infinity.

Understanding Infinity

Infinity isn't a standard number; it represents a concept of something without any bound or limit. It describes something that continues endlessly. Because of this, traditional arithmetic operations don't always apply in the same way they do with finite numbers.

Dividing Infinity

When we talk about dividing infinity by a number like one-half (0.5), we're essentially asking: "If we have something that's boundless and without end, and we take half of it, what do we have?"

Because infinity is already without limit, taking a portion of it (even a very small portion like one-half) doesn't make it any less limitless. Therefore, infinity divided by one-half remains infinity.

Example

Imagine you have an infinitely long line. If you cut that line in half, each piece is still infinitely long. This is similar to dividing infinity by 2 (or multiplying it by 1/2).

Mathematical Consideration

While not rigorous in the way you'd handle finite numbers, you can consider this concept related to limits. If you think of infinity as a limit tending towards an unboundedly large number, multiplying that by a constant like 1/2 still results in a limit tending toward infinity.

Conclusion

Because infinity is a concept of something without bound, dividing it by any finite number (including one-half) does not diminish its limitless nature. The result remains infinity.
