∞ and?are are both mathematical symbols, but they don't represent specific numbers, so they can't be compared according to the size relationship. ∞ is the symbol of infinity, which means that a number is greater than any finite number. Usually used to indicate that a number can increase infinitely under certain conditions. Is is an ancient Chinese character, which means "no" and is equivalent to "no". In mathematics, is is often used to represent unequal relations. For example, B means that A is not equal to B, so ∞ and?are is not the same type of symbol, so they cannot be compared in size. If you need to compare the size, you need to compare the specific number size.
