                  VertICAL MULtIPLICAtION

                  Vertical multiplication is another way to multiply the numbers. In this method, we

                  write a number below another number.
                                                                                                  t   O
                  Let us find 6 × 2.                                                                   6      Multiplicand

                                                                                              ×        2      Multiplier
                  We can write 6 × 2 = 12 as shown alongside.
                                                                                                  1    2      Product
                      Multiplicand

                                 Multiplier  Product
                  The number to be multiplied is called the multiplicand and the number by which

                  it is multiplied is called the multiplier. The answer is called the product.

                  example:  A car has 4 wheels. If there are 8

                  cars in a parking lot, how many wheels are                        Think and Answer
                                                                                 There  are  errors  in  the  given
                  there in all?                                                  multiplication grid. Spot the boxes
                  Solution:                                                      with errors and correct them.

                                                                  t    O           ×     1    2    3    4    5
                                Wheels in a car =                      4           6    6    14   16   24    48
                                Cars in the parking lot = ×            8           7    8    18   21   28    25

                                Wheels in all =                   3    2           8    8    19   26   48    40

                                Thus, there are 32 wheels in all.                  9    9    18   35   36    55
