When doing addition between integers, it is always easier to calculate the sum or difference between numbers that end with zero. For example:  $\begin{array}{l} {}\&{52+67+48}  {=}\&{52+48+67}  {=}\&{100+67}  {=}\&{167} \end{array}$  The same method can be applied to decimal calculations. Can you quickly get the answer of $$5.2+6.7+4.8$$?
