Explicație pas cu pas:

$\large \bf [ - 9 - ( - 7 + 3 + 9):( + 2 - 8 + 1)]:( - 4) =$

$\large \bf [ - 9 - ( + 5):( - 5)]:( - 4) =$

$\large \bf [ - 9 +1]:( - 4) =$

$\large \bf -8:( - 4) =$

$\color{red}\Large \boxed{\bf 2}$

                                   

$\large \bf [ + 2 - ( - 1 + 3 - 7):( + 7 - 6 - 2)]:( - 3) =$

$\large \bf [ + 2 - ( - 5):( -1)]:( - 3) =$

$\large \bf [ + 2+ 5:( -1)]:( - 3) =$

$\large \bf (+ 2-5):( - 3) =$

$\large \bf (-3):( - 3) =$

$\color{blue}\Large \boxed{\bf 1}$

                                   

$\large \bf [ + 35 + ( - 29 - 31 + 68):( - 41 + 37)]:( - 11) =$

$\large \bf [ + 35 +8:( - 4)]:( - 11) =$

$\large \bf ( + 35 -2):( - 11) =$

$\large \bf 33:( - 11) =$

$\color{indigo}\Large \boxed{\bf -3}$

                                   

$\large\bf + 48:[ - 26 + ( + 52 - 88):( - 46 + 29 + 15)] =$

$\large\bf + 48:[ - 26 -36:( - 2)] =$

$\large\bf + 48:(- 26 +18) =$

$\large\bf + 48:(- 8) =$

$\color{green}\Large\boxed{\bf -6}$
