Answer 1

Explicação passo-a-passo:

E)(-2-3)-}4+[-8-(-9+2)]}=

(-2-3)-{4+[-8-(-7)]}=

(-2-3)-{4+[-1]}=

(-2-3)-{3}=

(-5)-3=

-8

M)-(-5+1)+{-6-[2+(-3+6)]}=

-(-5+1)+{-6-[2+(3)]}=

-(-5+1)+{-6-5}=

-(-4)+{-11}=

-7

N)6-(-9+1)-}(-3+4)+[-(-5+1)+(-8+10)]}=

6-(-9+1)-{(-3+4)+[-(-4)+(2)]}=

6-(-9+1)-{(-3+4)+[6]}=

6-(-9+1)-{(1+6)+6}=

6-(-9+1)-{7+6}=

6-(-9+1)-{13}=

6-(-8)-13=

14-13=

1

O)-(-2)+(-3)-{-2+[-1-(-2+1)]+5}=

-(-2)+(-3)-{-2+[-1-(-1)]+5}=

-(-2)+(-3)-{-2+[0]+5}=

-(-2)+(-3)-{3}=

-1-3=

-4

P)20-{-10-[-8+(5-12)]-20)=

20-{-10-[-8+(-7)]-20}=

20-{-10-[-15]-20}=

20-{-10-[-35]}=

20-{25}=

-5

Espero ter ajudado ♥️.
