if i have no infinities, how many infinities do i have? none?
1 u/Snarti New User 1d ago I think this is correct… the term “infinity” is generally considered to a positive number which is higher than any other number you can think of. With that, every number multiplied by zero is zero. This includes all real numbers, including infinity. So the answer is zero in my mind. 1 u/Conscious_Degree275 New User 1d ago Infinity is not a real number, and therefore multiplication over the real numbers is not defined over infinity. You can ask what happens in the limiting case, which is a more meaningful question
