...work out A × B × 10f+g (note that we add the powers). So, for example 3 × 106 × 5 × 103 = 3 × 5 × 106+3 = 15 × 108 (which we could express as 1.5 × 109 if we want to make the number before the × take a value of between 1 and 10). On the other hand, to calculate A × 10f divided by B × 10g we simply work out (A ÷ B) × 10f−g (note that we subtract the...

...work. When trying to decide if some choices are better than others, you need to consider the key desirable properties of a database. The table here outlines some of them: Completeness Ensures that users can access the data they want.
