Simplify 12-11-(4+abs(-8-10+-7)+-13)+-7

 Esercizio

$12-11-\left(4+\left|-8+\left(-10\right)-7\right|-13\right)-7$

 

Applicare la formula: $a+b$$=a+b$, dove $a=12$, $b=-11$ e $a+b=12-11- \left(4+\left|-8-10-7\right|-13\right)-7$

$1- \left(4+\left|-8-10-7\right|-13\right)-7$

 

Applicare la formula: $a+b$$=a+b$, dove $a=1$, $b=-7$ e $a+b=1- \left(4+\left|-8-10-7\right|-13\right)-7$

$-6- \left(4+\left|-8-10-7\right|-13\right)$

 

Applicare la formula: $a+b$$=a+b$, dove $a=4$, $b=-13$ e $a+b=4+\left|-8-10-7\right|-13$

$-6- \left(-9+\left|-8-10-7\right|\right)$

 

Applicare la formula: $a+b$$=a+b$, dove $a=-8$, $b=-10$ e $a+b=-8-10-7$

$-6- \left(-9+\left|-18-7\right|\right)$

 

Applicare la formula: $a+b$$=a+b$, dove $a=-18$, $b=-7$ e $a+b=-18-7$

$-6- \left(-9+\left|-25\right|\right)$

$-6- \left(-9+\left|-25\right|\right)$
