multiplication grid as shown 1 11 12 13 14 15 16 17 18 19 20
here. 2 22 24 26 28 30 32 34 36 38 40
Suppose, we have to find 3 33 36 39 42 45 48 51 54 57 60
16 × 3. 4 44 48 52 56 60 64 68 72 76 80

Select the row showing 3 5 55 60 65 70 75 80 85 90 95 100
and the column showing 16. 6 66 72 78 84 90 96 102 108 114 120
The product of 16 × 3 is the 7 77 84 91 98 105 112 119 126 133 140

number at the intersection of 8 88 96 104 112 120 128 136 144 152 160
this row and column.
Thus, the product is 48. 9 99 108 117 126 135 144 153 162 171 180

Multiplying by Tens, Hundreds and Thousands

Multiply by Tens

� To multiply a number by 10, we multiply the number by 1 and put a zero, to the
right of the product.
For example, 4 × 10 = 40; 16 × 10 = 160; 53 × 10 = 530
