Answer 1

Resposta:

Explicação passo-a-passo:

j)10 + 5 - 6 - 8 + 5 - 1

  15- 14 +4

    1+4 = 5

k)(10 + 5)-(1+6 )

   15-7 = 8

l)7-(8-3)+1

 7-5+1 =3

m)25-10[+(7-4)]

   25-10[+3]  

   25-30 = -5

n)32+[10-(9-4)+8]

  32+[10-5+8]

  32-[5+8]

  32-13 = 19

o)45-[12-4+(2+1)]

  45-[12-4+3]

 45-[8+3}

 45-11= 34

p)70-[10-(5-1)]​

  70-[10-4]

  70-6= 64
