Answer 1

Respuesta:

$A) -13 + 18 - ( - 23 ) + ( - 14 ) - 8 =\\B) 25 -(-13)-37-(-9)+(-23)=\\C) -17*(-13)=\\D) -42/(-3)*(-5)=$

A)

$=-13+18-(-23)+(-14)-8\\= -13+18+23-14-8\\=6$

B)

$=25-(-13)-37-(-9)+(-23)\\=25+13-37+9-23\\=-13$

C)

$=-17*(-13)\\=((-)*(-))221\\=221$

D)

$=-42/(-3)*(-5)\\=-42/20\\=-2.8$
