Me ajudem pfv

Answer 1

k) -8+[4-(7-13)-1]+5
-8+[4+6-1]+5
-8+[9]+5
-8+9+5= 6

L) 1-{5-[32-(50-20)]}
1-{5-[32-30]}
1-{5-2}
1-3= 2

M) -13-[10-(7+5)]
-13-[10-12]
-13+2= -11

N) {5-[32-(50-20)]}
{5-[32-30]}
{5-[+2]}
5-2= 3

O) {16-[12+(20-25)]}
{16-[12-5]}
16-7= 9

P) 10-{30+[4-(5+2)]}
10-{30+[4-7]}
10-{30-3}
10-27= -17

Q) -2-{5-[3-(-3-1)]}
-2-{5-[3+4]}
-2-{5-7}
-2+2= 0


Espero ter ajudado!
