Suppose I am working on a problem and I wish to calculate the density of something. I measure the mass to be m = 24.5 grams and the volume is V = 10 cm 3. In this case the density would be: ALERT!

Sometimes we do not always need to give detailed answers to problems - we just want a rough idea. When we are faced with a large number, we could round it off to the nearest thousand, or nearest ...

Another way of rounding numbers is to count only the first few digits (maybe \(1\), \(2\) or \(3\) figures) that have a value attached to them. This method of rounding is called significant figures ...
