I'll admit that up until a month ago I had been absent for a couple of years, and only the title is encouraging me to come back. I was once in a group that has since died, and I took a perfunctory glance at the classifieds, but nothing struck me.
OTOH, this forum is pretty decent, so maybe it's not just title anymore (though it's certainly what brought me back). (Yesterday I was Heroic.)

Oh my god with you.
Surely you agree, as do all mathematicians and the math itself, that: a-a=0
Now if we are to give a the value of infinity, a=infinity, that is, then a-a=0 -> infinity-infinity=0
In one statement, a variable that has been given a value cannot be of a different value.
"In mathematics, "infinity" is often treated as if it were a number (i.e., it counts or measures things: "an infinite number of terms") but it is not the same sort of number as the real numbers. In number systems incorporating infinitesimals, the reciprocal of an infinitesimal is an infinite number, i.e. a number greater than any real number."
In other words: A common misconception is that infinity is an exact number. Infinity actually represents any number that is endless. Therefore, a infinity could be endlessly larger, endlessly smaller or anywhere inbetween the two.
The simpler way to say this is that give a the value of infinity, a=infinity this is not possible. Infinity is not a value. You cannot equate 'infinity' to anything. (( Unless you are comparing the cardinalities of different infinite sets, but that's a whole other ball game entirely, and what happens when you try and define 'infinity'. See Set Theoretic Infinity if interested. ))
