JAWABAN :
NO 1 :
9(3) - 6(2) =
= 9(3) - 6(2)
= ( 9 × 3 ) - ( 6 × 2 )
= ( 9 + 9 + 9 ) - ( 6 + 6 )
= ( 18 + 9 ) - 12
= 27 - 12
= 15
________________________________
NO 2 :
7(5) - 5(4) =
= 7(5) - 5(4)
= ( 7 × 5 ) - ( 5 × 4 )
= ( 7 + 7 + 7 + 7 + 7 ) - ( 5 + 5 + 5 + 5 )
= ( 14 + 7 + 7 + 7 ) - ( 10 + 5 + 5 )
= ( 21 + 7 + 7 ) - ( 15 + 5 )
= ( 28 + 7 ) - 20
= 35 - 20
= 15
