Although the model is structural and makes reference to an apparatus, the id, ego and super-ego are purely psychological concepts and do not correspond to (somatic) structures of the brain such as the kind dealt with by neuroscience.
it takes a thousand million to make a billion, so 1,000,000 = 1 million 1,000,000,000 = 1 billion divide 142.98 by 1000= .14298 usually only convert if you have a thousand or â¦more millions. for instance, the US population is 300 million, or .3 billion. but nobody says that.
trillion = (million)^3 = (10^6)^3 = 10^18. trillion = 1,000,000,000,000,000,000,000,000. In science, we do not use these number names any more. We use scientific notation, which makes it obvious that 10^12 (10 raised to the 12th power) is different from 10^18.
