Each instruction in quadruples presentation is divided into four fields: operator, arg$1,$ arg$2,$ and result. The above example is represented below in quadruples format:
$(a+b)>(c+d)$ OR $a>c$ AND $b<d$
$(t1>t2)$ OR $a>c$ AND $b<d$
$t3$ OR $t4$ AND $t5$
$t3$ OR $t6$
$t1= a+b$
$t2= c+d$
$t3= t1>t2$
$t4= a>c$
$t5= b<d$
$t6= t4$ AND $t5$
$t7 =t3$ OR $t6$
\begin{array}{|l|l|l|l|} \hline \text{Op} & \text{arg1} & \text{arg2} & \text{Result} \\\hline \text {+} & \text{a} & \text{b} & \text{t1} \\\hline \text {+} & \text{c} & \text{d} & \text{t2} \\\hline \text {>} & \text{t1} & \text{t2} & \text{t3} \\\hline \text {.>} & \text{a} & \text{c} & \text{t4} \\\hline \text {<} & \text{b} & \text{d} & \text{t5} \\\hline \text {AND} & \text{t4} & \text{t5} & \text{t6} \\\hline \text {OR} & \text{t3} & \text{t6} & \text{t7} \\\hline \end{array}
