Applicare la formula: $\frac{a}{b}+c$$=\frac{a+cb}{b}$, dove $a/b+c=\frac{85}{164}-2.3193$, $a=85$, $b=164$, $c=-2.3193$ e $a/b=\frac{85}{164}$

Applicare la formula: $ab$$=ab$, dove $ab=-2.3193\cdot 164$, $a=-2.3193$ e $b=164$

Applicare la formula: $a+b$$=a+b$, dove $a=85$, $b=-380.3652$ e $a+b=85-380.3652$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=-295.3652$, $b=164$ e $a/b=-\frac{295.3652}{164}$
