Jawaban:

Tabel nomor 1 =

a + b = 1 + (–6)

b + a = (–6) + 1

(a + b) + c = (1 + (–6)) + (–11)

a + (b + c) = 1 + ((–6) + (–11))

Tabel nomor 2 =

a + b = 2 + 7

b + a = 7 + 2

(a + b) + c = (2 + 7) + (–12)

a + (b + c) = 2 + (7 + (–12))

Tabel nomor 3 =

a + b = 3 + 8

b + a = 8 + 3

(a + b) + c = (3 + 8) + 13

a + (b + c) = 3 + (8 + 13)

Tabel nomor 4 =

a + b = (–4) + 9

b + a = 9 + (–4)

(a + b) + c = ((–4) + 9) + 14

a + (b + c) = (–4) + (9 + 14)

Tabel nomor 5 =

a + b = (–5) + (–10)

b + a = (–10) + (–5)

(a + b) + c = ((–5) + (–10) + 16

a + (b + c) = (–5) + ((–10) + 16)

Semoga membantu.
