edu1247: {-20+(-7+9) elevado a 3 -(-7+9-(-1+5)]-(-1) elevado a 3}
edu1247: -5 elevado a 2+(-3)(-1+7)-[+3-5 (-1+2)]
edu1247: {12-(-5+9)elevado a 2-[+5-(-2+13)]elevado a 0-(-5+3)}
nicolepaivasant63: 1°={-20+(+343+727)-(-7+9+1-5)-(+1)
{-20+1072+7-9-1+5-1}=
{1084-31}=
1053
nicolepaivasant63: 2º=+25-3.(-1+7)-[+3-5-1+2]=
+25+3-21-3+5+1-2=
+34-26
+8
nicolepaivasant63: 3°={+12-(+25+81)-[+5+2-13]°+5-3}
{+12-25-81+0+5-3}=
{-109+17}=
-92
