Multiplication 6th Table

If a box contains 6 chocolates, how many chocolates are there in 10 such boxes? Shall we calculate the number of chocolates in boxes?

Number of chocolates,

one box = \( 6 = 6 \times 1 = 6 \)

two boxes = \( 6 + 6 = 6 \times 2 = 12 \)

three boxes = \( 6 + 6 + 6 = 6 \times 3 = 18 \)

four boxes = \( 6 + 6 + 6 + 6 = 6 \times 4 = 24 \)

Ten boxes = \( 6 + 6 + \dots 10 \text{ times} = 6 \times 10 = 60 \)

Multiplication is the shortest form of repeated addition.
EXAMPLE

If 6 fans are needed for one room. How many fans are needed for 9 rooms?

Solution:

To find the total fans we have to multiply 9 by 6.

54 fans are needed for 9 rooms.

\( 9 \times 6 = 54 \)

Exercise 2.2

1. \( 4 \times 6 = \) 24

2. \( 7 \times 6 = \) 42

3. \( 8 \times 6 = \) 48

4. In a shirt there are 6 buttons, how many buttons will there be in 8 shirts?

No. of buttons in 1 shirt = 6

No. of buttons in 8 shirts = \( 8 \times 6 \)

= 48

Answer: There will be 48 buttons in 8 shirts.

5. In a carton, there are 9 rows with 6 eggs in each row. How many eggs are there in all?

No. of eggs in 1 row = 6

No. of eggs in 9 rows = \( 9 \times 6 \)

= 54

Answer: There are 54 eggs in all.
