11 Times Table – Explanation & Examples

The 11 times table is the multiplication table for the number 11. Eleven is a prime number, but unlike the prime number 7, the table of 11 is quite easy to familiarize with.

The 11 times table is a table that contains multiples of the number 11.

Learning and understanding the 11 times table is essential for solving multiplication, division, and factorization problems. This topic will present some tips that will help students memorize the 11 times table.

11 Multiplication Table

We can write the table of 11 as:

  • $11\times 1 = 11$
  • $11\times 2 = 22$
  • $11\times 3 = 33$
  • $11\times 4 =44$
  • $11 \times 5 =55$
  • $11 \times 6 =66$
  • $11 \times 7 = 77$
  • $11 \times 8 = 88$
  • $11 \times 9 = 99$
  • $11 \times 10 = 110$

Tips on Learning the 11 Times Table

Let us look at some simple tips which can help you memorize the 11 times table.

Digits pattern for the first 9 multiples: The first nine multiples follow a simple pattern. The number which is multiplied by 11 is repeated twice in the product. For example, $11\times 1 = 11$, as 11 is multiplied by the number 1, 1 is repeated in the answer  which is 11. Similarly,  $11\times 6 =66$, here 6 is repeated. The whole pattern is presented below, and the repeated digits are shown in green color.

Pattern for the 10th and higher multiples of 11: This method presents the pattern followed by the 10th and the higher multiples of the number 11. Suppose 11 is multiplied by 10 (note that the unit digit of 10 is 0 and the tens digit is 1); the product of $11 \times 10$ is equal to 110 (unit digit 0, tens digit 1, and hundreds digit 1). The unit digit of the product is the same as the unit digit of the number multiplied by 11.

The tens digit of the product is the summation of the unit and the tens digit. In our example, 10 is being multiplied by 11, so the tens digit of the product is $0+1 = 1$. Lastly, the hundreds digit of the product is the same as the tens digit of the number multiplied by 11. In short, the unit and hundreds digit of the number 10 are equal to the unit and tens digit of the product, i.e., 110. Meanwhile the ten’s digit of the product is the summation of the unit and tens digit of 10, i.e., $1+0 =1$.

This pattern is presented in the table below. Note that the only exception is the 19th multiple of 11.  The summation of the unit and ten’s digit of 19 leads to $1+9 =10$.  So 0 will be the ten’s digit of the product while 1 will be added in the hundred’s digit of the product, and it will become $1+1 =2$, as shown in the table below.

Using the 10 times table: This is one of the easiest methods to learn the 11 times table, if you have already memorized the 10 times table. If we add natural numbers to multiples of the number 10, we get the 11 times table.

The first multiple of 10 is added with the first natural number which is 1. Similarly, the second multiple of 10 is added with the second natural number 2. This method is presented in the table below.

Example 1:  Calculate 11 times 4 times 2 minus 40.

Solution:

11 times 4 times 2 minus 40 can be written as:

$ 11\times4 \times 2 – 40$

$ =44\times 2 – 40$

$ = 88 – 40$

$ = 48$

Example 2: Verify whether the 7th  multiple of 11 is 77 or not.

Solution:

We know the first 7 multiples of 11 are 11, 22, 33, 44, 55, 66, and 77.

We can also verify it through the addition method.

Hence, we can confirm that the 7th multiple of 11 is 77.

Example 3: May has enough chocolates to give her 3 friends 11 chocolates each. Calculate the total number of chocolates she has.

Solution:

May distributes 11 chocolates each to 3 friends.

By using the 11 times table, we can calculate the total number of chocolates.

$11\times 3 = 33$ chocolates

Example 4: Using the digit pattern method, find the values of

  • 11 times 43
  • 11 times 52

Solution:

To find $11 \times 43$, we note that the unit digit of the product would be the same as the unit digit of $43$, i.e., 3. The hundredth digit of the product would the same as the tens digit of $43$, i.e., 4, and the tens digit of the product would be the sum of $4$ and $3$, i.e., 7. Hence, the product is 473.

To find $11 \times 52$, we note that the unit digit of the product would be the same as the unit digit of $52$, i.e., 2. The hundredth digit of the product would the same as the tens digit of $52$, i.e., 5, and the tens digit of the product would be the sum of 5 and 2, i.e., 7. Hence, the product is 572.

Answer Key

1) We know that one bag contains 4 balls.

So 11 bags will have $11\times 4 = 44$ balls.

2) We can write 11 times 2 times 2 as:

$ 11\times 2 \times 2$

$ = 22 \times 2$

$ = 44$

3) $ Y \times 11 = 11\times 4 – 11$

$ Y \times 11 = 44 – 11 $

$ Y \times 11 = 33 $

We know $11\times 3 =33$, so $ Y = 3 $.
