what is = to infinity? infinity is not a real number, for example, 1+2+3+4+5+6+7+8+9+........ will be infinity or not we don't know, but what we know is this number is closer and closer to infinity, just like when 1/(very large number) = about 0 when 1/(more large number) = closer to 0 when 1/(the greatest number possible)= infinity, but there is not a number that is the greatest so infinity does not exist, but is dose not another way, we can get it when we don't do any mathematics calculation.
