Right but my son if having been taught long division might get the digit answer and then look at it and figure out he needs to move the decimal because his answer couldn't possibly be right without ever being taught to move your decimal because he just gets math like that. Some people have to be taught to check long division with multiplication and he can just look at it and mentally check it in his head. Like if he had been taught to long divide 1000 by 5. And then got a problem to divide 1000 by .5. He would know 200 wasn't right just by his number sense and then use logic to add a zero. And then mentally check it by multiplying.
