Answer 1

-6+5-(7-4)+3= -6+5-7+4+3= 12-13= -1 -2-5(2-7)-(5+6)= -2-10+35-5-6= 35-23= 12 3-7+(-9-3)-(1-2)= 3-7-9-3-1+2= 5-20= -15 -(5-2)+(4-6)-(8+2)= -5+2+4-6-8-2= 6-21= -15 -(6-3)-[2-(5-7)-3]= -6+3-[2-5+7-3]= -6+3-2+5-7+3= 11-15= -4 2+{-[-7+8]+(4-3)}-2= 2+{-[-7+8]+4-3}-2= 2+{7-8+4-3}-2= 2+7-8+4-3-2= 13-13= 0 -5[-(4-7)-(2-3)]= -5[-4+7-2+3]= 20-35+10-15= 30-50= -20 -(7-3)-(5-2)-[(12-6)-(9-5)]= -7+3-5+2-[12-6-9+5]= -7+3-5+2-12+6+9-5= 20-29= -9 LISTO! Espero haberte ayudado!
