Less digits to work with. As an example, to multiply 4000 x 30,000, you only need to multiply 4 x 3, then attach all the zeros (7 zeros in this case) at the end. WITH A LITTLE BIT OF PRACTICE, YOU CAN DO THIS CALCULATION IN YOUR HEAD. However, if there are more significant digits (roughly speaking, non-zero digits), most people would need pencil and paper, or a calculator, to do such a calculation.
Rounded numbers are easier to work with because in each number, there are fewer significant digits to work with.
