Hitunglah hasil dari 8 + (-16) – (-25) – (-4) = -15 – (-9) + (-18) – (-22) = Menggunakan sifat distribusi, tentukan 12 x (6 + 3) = (6 x 4) – (6 x 2) = PEMBAHASAN 1. Hasil dari 8 + (-16) – (-25) – (-4) = -8 + 29 = 21 -15 – (-9) + (-18) – (-22) = -6 + 4 = -2 2. Menggunakan Sifat Distribusi 12 x (6 + 3) = (12 x 6) + (12 x 3) = 108 (6 x 4) – (6 x 2) = 6 x (4-2) = 12 Azizah Production Are you sure wanna exit ? Yes No
