Question: User: \infty+\infty=$\omega$
1. The problem states the expression $\infty + \infty = \omega$. 2. Here, $\infty$ represents infinity, which is not a real number but a concept describing unbounded growth. 3. In standard mathematics, adding infinity to infinity is still considered infinity, i.e., $\infty + \infty = \infty$. 4. The symbol $\omega$ often represents the first infinite ordinal in set theory, which is a different concept from the arithmetic infinity $\infty$. 5. Therefore, the expression $\infty + \infty = \omega$ is not generally true in arithmetic but may have meaning in ordinal arithmetic where $\omega + \omega$ is a well-defined ordinal. 6. In ordinal arithmetic, $\omega + \omega$ is the ordinal after all finite sums of $\omega$, which is different from $\omega$ itself. 7. To summarize, $\infty + \infty = \infty$ in extended real numbers, but $\omega + \omega > \omega$ in ordinal numbers. 8. Hence, the original expression mixes two different concepts and is not an equality in standard arithmetic.
