-[-85÷17+8]-(4) (-7)÷2}



24÷6÷2+2(7-9) (-4)



{3[-9(-8)÷-6-7]+2

Answer 1

Respuesta:

$( - 3 + 8 + 13 - 6) \div (8 - 12 + 7 - 9) \\ ( - 9 + 21) \div (15 - 21) \\ 12 \div ( - 6) = - 2$

Explicación paso a paso:

$- ( - 85 \div 17 + 8) - (4)( - 7) \div 2 \\ - (5 + 8) + 28 \div 2 \\ - 13 + 14 = 1$

$24 \div 6 \div 2 + 2(7 - 9)( - 4) \\ 12 \div 2 + 2( - 2)( - 4) \\ 6 + ( - 4 \times - 4) \\ 6 + 16 = 22$

{3[-9(-8)÷-6-7]+2

{3[72/-6-7]+2

3[12-7]+2

3*5+2

15+2=17
