Nobody's head is perfectly round. It is a free-form shape. Everybody's is a different shape.

Why do you round off numbers?

You round off numbers for several reasons. First, your final answer is no more accurate than your original measurement. If you do not round off, you will give an inaccurate picture of your measurement. Second, you round off numbers to check electronic equipment. You can not begin to add, subtract, multiply, and divide in your head as fast as an electronic piece of equipment. Still, by rounding off numbers, you can get a rough idea of what the answer should be. If the answer the computer gives is nowhere near your answer then something could be drastically wrong with some spread sheet formula. You round off money real fast to know if you have been cheated.
