When phosphorus is reacted with concentrated sulfuric acid, phosphoric acid, sulfur dioxide and water are formed. $a\text{H}_2\text{SO}_4 + b\text{P} \rightarrow c\text{H}_3\text{PO}_4 + d\text{SO}_2 + e\text{H}_2\text{O}$ $a$, $b$, $c$, $d$ and $e$ each represent whole numbers. This equation may be balanced by applying oxidation numbers. Find the value of the total $a + b + c + d + e$?
