Applicare la formula: $x,\:a,\:b,\:c$$=eval\left(x,a,b,c\right)$, dove $a=a=3$, $b=b=4$, $c=c=\frac{1}{3}$, $x=\frac{a}{c}+\frac{b}{d}$ e $x;a=\frac{a}{c}+\frac{b}{d},\:a=3,\:b=4,\:c=\frac{1}{3}$

Applicare la formula: $\frac{a}{\frac{b}{c}}$$=\frac{ac}{b}$, dove $a=3$, $b=1$, $c=3$, $a/b/c=\frac{3}{\frac{1}{3}}$ e $b/c=\frac{1}{3}$
