The expression "1 infinity + 1 infinity + 1 infinity" is not mathematically well-defined because infinity is not a number in the traditional sense; rather, it is a concept representing an unbounded quantity.
In standard arithmetic, adding infinities does not yield a meaningful result in the same way that adding finite numbers does. Instead, we often use concepts from calculus or set theory to deal with infinity in a more precise manner.
If you are referring to limits or cardinalities in set theory, you would need to specify the context in which you want to frame the question. For example, in some contexts, you might argue that the sum of countably infinite quantities leads to a specific type of infinity, but this depends on the definitions used.
In summary, your statement isn't accurate in a conventional mathematical sense. Would you like more clarification on any specific aspect?
