                                                                                                  3 × 4 = 12




                                                                                                  4 × 3 = 12



        Thus, 3 × 4 = 4 × 3


        Multiplying by 1


        Any number multiplied by 1 gives
        the product as the same number.                                   5 × 1 = 5                7 × 1 = 7


        Multiplying by 0


        Any  number  multiplied  by  0
        gives the product as 0.                                           6 × 0 = 0                3 × 0 = 0


         Fill in the blanks.


               (a)  3 × 5 = _____ × 3                       (b) _____ × 2 = 2 × 7

               (c)  6 × 4 = _____ × 6                       (d) 8 × _____ = 5 × 8



         Write the answers.


               (a)  1 × 5 = ____                            (b) 8 × 0 = ____

               (c)  6 × 1 = ____                            (d) 4 × 0 = ____



         Fill in the boxes.


               (a)  6 × 4 =            = 4 × 6              (b) 7 × 3 =             = 3 ×


               (c)  6 × 2 =            = 2 ×                (d) 8 × 0 =             = 0 ×
