Question

14 + { −7 + [ 4 − 11 + ( 5 − 4) − (−6 + 8 − 3 )] + 7}=?

Answer 1

Răspuns: $\color{red}\Large\boxed{ \bf 9}$

Explicație pas cu pas:

$\large \bf 14 + \{ -7 + [ 4 - 11 + ( 5 - 4) -(-6 + 8 - 3 )] + 7\}=$

$\large \bf 14 + \{ -7 + [ 4 - 11 + 1 -(2 - 3 )] + 7\}=$

$\large \bf 14 + \{ -7 + [ 4 - 11 + 1 -(-1 )] + 7\}=$

$\large \bf 14 + [ -7 + (4 - 11 + 1 +1 ) + 7]=$

$\large \bf 14 + [ -7 + (-5) + 7]=$

$\large \bf 14 + (-7 -5 + 7)=$

$\large \bf 14 + (-12 + 7)=$

$\large \bf 14 + (-5)=$

$\large \bf 14 -5=$

$\color{red}\Large\boxed{ \bf 9}$
