Jawaban:
a \times× (b + c) = (a \times× b) + (a \times× c)
a \times× (b - c) = (a \times× b) - (a \times× c)
PEMBAHASAN
A. (15 \times× 32) + (15 \times× 18)
(15 \times× 32) + (15 \times× 18) = 15 \times× (32 + 18)
= 15 \times× 50
= 750
B. (8 \times× 41) + (8 \times× 59)
(8 \times× 41) + (8 \times× 59) = 8 \times× (41 + 59)
= 8 \times× 100
= 800
C. (27 \times× 112) - (27 \times× 12)
(27 \times× 112) - (27 \times× 12) = 21 \times× (112 - 12)
= 21 \times× 100
= 2.100
D. (150 \times× 32) - (150 \times× 12)
(150 \times× 32) - (150 \times× 12) = 150 \times× (32 - 12)
= 150 \times× 20
= 3.000
E. 3 \times× 483 = 3 \times× (400 + 80 + 3)
3 \times× 483 = 3 \times× (400 + 80 + 3)
= (3 \times× 400) + (3 \times× 80) + (3 \times× 3)
= 1.200 + 240 + 9
= 1.449
