Table of 22

Introduction:

The table of 22, a fundamental tool in arithmetic, is created through repeated addition of the number 22. By following this process, each number in the table represents the product of 22 and a whole number. The fact that 22 is a prime number and the product of two prime numbers (2 and 11), makes it a unique and valuable tool for understanding the patterns and properties of multiplication. The ability to recall the times table of 22 and other numbers allows for faster and more efficient mental calculation, making it a valuable skill for problem-solving and arithmetic mastery.

Mathematical Operations to Calculate Tables:

A times table can be calculated by using two mathematical operations.

a) Multiplication

The table of multiplication can be obtained by multiplying a number with a set of whole numbers. Multiplication is one of the basic mathematical operations and most commonly used approach to get the multiplication tables.

For example, multiplication table of 5 is given by:

5 × 1 = 5

5 × 2 = 10

5 × 3 = 15

b) Repeated Addition

Repeated addition is adding equal groups together, which is the same as the multiplication. If the exact number is repeated, then we can write repeated addition in the form of multiplication. Repeated addition is also helpful in learning multiplication facts. For example if you are not familiar with 4 × 3 , you may find it easier to work out 4 × 3 by writing 3 + 3 + 3 + 3 or 4 + 4 + 4; and then slowly adding. It may also be helpful with larger numbers, such as 7 × 50. It is more comfortable writing 50 + 50 + 50 + 50 + 50 + 50 + 50 and then adding on the tens.

● The concept of repeated addition is introduced to children in an interactive and engaging manner, which helps them to grasp the idea of multiplication.

● By solving repeated addition problems, kids can understand the relationship between addition and multiplication, which is crucial for solving more complex math problems in the future.

● It is a simple yet effective way of learning basic multiplication facts and helps with building a strong foundation for advanced mathematical concepts.

● Repeated addition is also a fun and interactive way for kids to learn and explore the world of numbers, and it can be used to reinforce their understanding of arithmetic operations.

Tips for 22 Times Table:

1. To memorise the 22 times table, we first need to memorise the 2 times table. The first 10 multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20.

2. The digits are always the whole number we multiply with. The digit in one's place is an even number obtained by multiplying 2 with the whole number and then add the ten's place.

3. We can find the product of 22 with any number by multiplying the number by 2 first. From the number 5, we then add up the products. For example, 22 times 6 = (2 times 6) + (2 times 6) = 12 + 12 = (12+1)2 = 132 and 22 times 9 = (2 times 9) + (2 times 9) = 18 + 18 = (18+1)8 = 198.

Solved Problems of Table 22:

Example-1:

A shopkeeper has 22 pen boxes in his shop. If each box has 25 pens, then find the total number of pens?

Solution:

Given,

Number of pen boxes = 22

Number of pens in a pen box = 25

Using the table of 22, 22 × 25 = 550.

Thus, the total number of pens in the shop = 22 × 25 = 550

\begin{equation}

22 \times 25=550

\end{equation}

Example-2:

The price of a book is 22 rupees. If Mahesh wants to buy 32 books, how much should he pay?

Solution:

Given,

Price of each book = 22

Number of books Mahesh wants to buy = 32

Using the table of 22, 22 × 32 =704.

Therefore, to buy the total number of books, Mahesh should pay = 22 × 32 = 704 rupees.

\begin{equation}

22 \times 32=704

\end{equation}

Example-3:

If Arjun can walk 7 kilometres per hour, how much distance will he cover in 22 hours?

Solution:

Given,

Distance travelled by Arjun in one hour = 7

Total time Arjun travelled = 22

Using the table of 22, 7 × 22 = 154.

Therefore, the total distance travelled by Arjun in 22 hours = 22 × 16 = 154 km.

\begin{equation}

7 \times 22=154

\end{equation}

Example-4:

A carton contains 22 boxes of nails, and each box weighs 3 kg. How much would a carton of nails weigh?

Solution:

Given,

Total number of boxes = 22

Weight of each box = 3

Using the table of 22, 22 × 3 = 66.

Therefore, the total weight of carton of nails = 22 × 3 = 66 kg

\begin{equation}

22 \times 3=66

\end{equation}

Example-5:

If a car travels at 22 km per hour, how much distance will it cover in 10 hours?

Solution:

Given,

Distance travelled by a car in one hour =22

Total time travelled = 10

Using the table of 22, 22 × 10 = 220.

Therefore, the total distance travelled by car in 10 hours = 22 × 10 = 220 km.

\begin{equation}

22 \times 10=220

\end{equation}
