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.
  One billion is 1,000,000,000. one thousand is 1,000. Divide 1,000 into 1,000,000,000 and the result is 1,000,000 (one million) therefore there are one million thousands â¦ in one billion. Until fairly recently one billion was refered to as one thousand million.
