  • 1] 12 × 5
    = 5 × 12
    = 60

    2] ( 16 × 4 ) × 12
    = 16 × ( 4 × 12 )
    = 16 × 48
    = 768

    3] 13 × ( 12 + 8 )
    = ( 13 × 12 ) + ( 13 × 8 )
    = 156 + 104
    = 260

    4] ( 15 × 6 ) + ( 15 × 4 )
    = 15 × ( 6 + 4 )
    = 15 × 10
    = 150

    5] ( 14 × 8 ) - ( 14 × 2 )
    = 14 × ( 8 - 2 )
    = 14 × 6
    = 84
  • 1)12 x 5=             ⇒Komuitatif
       5 x 12=
       60

    2)(16 x 4)x12=     ⇒Asosiatif
       16 x (4x12)=
        16 x 48=
       768

    3)13 x(12+8)=        ⇒Distributif
    (13 x 12)+(13 x 8)
        156 + 104=
         260

    4)(15 x 6)+(15 x 4)       ⇒Asosiatif
        15 x (6+4)
        15 x 10
        =150

    5)(14 x 8)-(14 x 2)        ⇒Asosiatif
        14 x(8 - 2)
        14 x 6
      =84
