21 | x | 10 | = | 210 |

The 21 times table is a mathematical table that lists the products of 21 and positive integers up to a certain limit. The table starts with 21 × 1 = 21, and each subsequent row lists the product of 21 and the next integer. The table usually goes up to 10 or 12.

Here's the full 21 times table:

- 21 x 1 = 21
- 21 x 2 = 42
- 21 x 3 = 63
- 21 x 4 = 84
- 21 x 5 = 105
- 21 x 6 = 126
- 21 x 7 = 147
- 21 x 8 = 168
- 21 x 9 = 189
- 21 x 10 = 210

The multiples of 21 are numbers that can be evenly divided by 21. Some of the first few multiples of 21 are:

21, 42, 63, 84, 105, 126, 147, 168, 189, 210, ...

In general, to find the nth multiple of 21, you can multiply 21 by n.
Here is the 21-times table written in words:

- One times twenty-one is twenty-one
- Two times twenty-one is forty-two
- Three times twenty-one is sixty-three
- Four times twenty-one is eighty-four
- Five times twenty-one is one hundred five
- Six times twenty-one is one hundred twenty-six
- Seven times twenty-one is one hundred forty-seven
- Eight times twenty-one is one hundred sixty-eight
- Nine times twenty-one is one hundred eighty-nine
- Ten times twenty-one is two hundred ten
- Eleven times twenty-one is two hundred thirty-one
- Twelve times twenty-one is two hundred fifty-two

21 times 21 is equal to 441

The product of 21 and 22 means

21 x 22 = 462

So, the answer is 462.The number 21 is a significant number that appears frequently in mathematics, science, and culture. It is the product of 3 and 7, making it a highly composite number with many factors.

In mathematics, 21 is significant as it is a triangular number, which is a number that can be represented as a triangle of dots. It is also a Harshad number, which means that it is divisible by the sum of its digits.

In science, 21 is significant in many ways. For example, there are 21 known isotopes of gold, which is a chemical element that is used in many applications, such as jewelry and electronics. It is also the atomic number of scandium, which is a chemical element that is used in many alloys.

In culture, 21 often represents coming of age or maturity, as in the American tradition of the 21st birthday celebration. In some cultures, 21 is also associated with good luck and fortune.

Overall, the number 21 is a significant and interesting number that appears frequently in many different areas of study.
