            Multiplication Grid for Tables of 11 to 20

            We can fi nd products of 2 numbers with the help of multiplication grid as shown here.

            Suppose, we have to              ×      11     12     13     14     15     16     17     18     19     20

            fi nd 16 × 3.
                                             1      11     12     13     14     15     16     17     18     19     20
            Select the row showing
            3 and the column                 2      22     24     26     28     30     32     34     36     38     40
            showing         16.     The      3      33     36     39     42     45     48     51     54     57     60
            product of  16 × 3 is

            the number at the                4      44     48     52     56     60     64     68     72     76     80
            intersection of this row         5      55     60     65     70     75     80     85     90     95    100
            and column. Thus, the            6      66     72     78     84     90     96    102 108 114 120
            product is 48.
