When written in English, 4 can be written as Four. We would normally use the place value system to come to this conclusion. But since we only have one number, which will be placed in the ones place, we will use the name given to this number. For example, if you bought 4 sweets from a shop, then you can say ‘i will share four of these sweets with my friends”.

We generally use the place value system to name our numbers. But before we do that, let's learn the names of the first 10 numbers we should all learn.

Cardinal Number | Number in Words |

0 | Zero |

1 | One |

2 | Two |

3 | Three |

4 | Four |

5 | Five |

6 | Six |

7 | Seven |

8 | Eight |

9 | Nine |

10 | Ten |

Now that we have learned the names of the numbers from 0 - 10, let's see the place value for the number 4.

Thousand | Hundred | Tens | Ones |

x | x | x | 4 |

As we can see, the number 4 takes it places in the ones place. Therefore, we will simply call it by its original name, which is Four.

The number 4 can be represented mathematically as follows

\begin{aligned}

&0 \times \text{Thousand} + 0 \times \text {Hundred} + 0 \times \text{Tens} + 4 \times \text {Ones}\\

&= 0 \times 1000 + 0 \times 100 + 0 \times 10 + 4 \times 1\\

&= 0 + 0 + 0 + 4\\

&= 4 = \text{FOUR}\\

\end{aligned}

Following are some of the properties of number 4 that we must keep in mind

4 is an even number because it can be completely divided by the number 2. Look at the following equation for reference

\begin{aligned}

&4/2 = 2

\end{aligned}

4 is not a prime number. This is because it has more than 2 factors, which are numbers that can completely divide it. Following are the factors of the number 4

\begin{aligned}

&1, 2, 4\\

\end{aligned}

4 is a perfect square of the number 2. This means that if 2 is multiplied by itself, it will give us the number 4.

\begin{aligned}

&2^2 = 2 \times 2\\

&\hspace{4mm} = 4 = \text {FOUR}

\end{aligned}

Square of 4 is 16 and the cube of 4 is 64.

\begin{aligned}

&4^2 = 4 \times 4\\

&\hspace{4mm} = 16 = \text {Sixteen}

\end{aligned}

\begin{aligned}

&4^3 = 4 \times 4 \times 4\\

&\hspace{4mm} = 64 = \text {Sixty Four}

\end{aligned}

**You can find out the detailed other number in words article list below:-**

1. How do you write 4 in words?

In English 4 can be written as Four.

2. What are 2+2 and 2x2? Are they the same?

The above problems can be solved as follows

\begin{aligned}

&2 + 2 = 4\\

&\\

&2 \times 2 = 4

\end{aligned}

As we can see, both of their answers are 4 (which can be written as Four in words).

3. Why is 4 not an odd number?

Since 4 can be completely divided by the number 2, it is an even number, not an odd number.

4. What do you mean by Cardinal Number?

Whenever we give any value to a thing, that value is known as a cardinal number. For example, if there are 4 trees in the yard, then 4 is a cardinal number.

5. Do we need a place value system to write 4 in words?

We can use the place value system to understand what is the position of the number 4, but as it is a single-digit number, we can directly call it by its name, which is Four.
