Given, 8 × 3 ' × ' imply multiplication. Multiplication can be defined as a form of repetitive addition. 8 × 3 imply 8 times 3 . 8 × 3 = 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 24 8 × 3 = 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 24 Therefore, the required answer is 24 .

' × ' imply multiplication. Multiplication can be defined as a form of repetitive addition. Multiplication of any number with 3 implies adding the number to itself three times. Few examples are given below: 3 × 2 = 2 + 2 + 2 = 6 3 × 4 = 4 + 4 + 4 = 12 3 × 5 = 5 + 5 + 5 = 15 3 × 6 = 6 + 6 + 6 = 18 There are many more such examples and the blanks can be filled using any such example.

' × ' imply multiplication Here, 42 is the product of the multiplication. The number 42 can be written as product of 7 and 6 , 21 and 2 , 14 and 3 , 42 and 1 as shown below: 7 × 6 = 42 21 × 2 = 42 14 × 3 = 42 42 × 1 = 42 One of the above given combination of multiplicand and multiplier can be used to fill the given blanks.

Given, 5 × _____ = 40 . Now, let us use the multiplication table of 5 to find the multiplicand. From the multiplication table of 5 , we get, 1 × 5 = 5 2 × 5 = 10 3 × 5 = 15 4 × 5 = 20 5 × 5 = 25 6 × 5 = 30 7 × 5 = 35 8 × 5 = 40 Hence, 5 × 8 = 40 . The required number is 8 .
