As we have done quite a lot of this earlier, let us see if we remember which is the **greatest** among these :

Let us do some more comparison problems.

### Find greatest and smallest numbers:

**1)Based on number of digits:**

**Greatest :****Smallest :****Greatest :****Smallest :****Greatest :****Smallest :****Greatest :****Smallest :**

Was that easy?

We just looked at the number of digits and found the answer.The greatest number has the most **thousands** and the smallest is only in **hundreds** or in **tens**.

**2) When number of digits is same :**

- They both have
digits. - But, the digit at the thousands place in 4875 is
that in 4879. - Let us move to the next digit. The digit at the hundreds place in 4875 is
that in 4879. - Let us move to the tens place. The digit at the tens place in 4875 is
that in 4879. - Let's compare the digits at the ones place. The digit at the ones place in 4875 is
that in 4879. - Thus, 4875 is less than 4879.

Now, let us solve some more problems.

## How many numbers can you make?

Suppose, we have four digits 7, 8, 3, 5. Using these digits we want to make different 4-digit numbers in such a way that no digit is repeated in them. Thus, 7835 is allowed, but 7735 is not. Make as many 4-digit numbers as you can.

**Which is the greatest number you can get with 7,8,3,5?**

**The greatest number we can get with 7,8,3,5 **

**Which is the smallest number you can get with 7,8,3,5?**

**The smallest number we can get with 7,8,3,5 .**

**Think about the arrangement of the digits in both. Can you say how the largest number is formed?**

**The numbers are arranged in order.**

**How about the smallest number?**

**The numbers are arranged in order.**

How many possible combinations of 4 digit numbers you can make using these 4 numbers? We can make

It is 24 combinations because there are 4 choices for the first digit, 3 remaining choices for the second digit, 2 choices for the third digit, and 1 choice for the last digit, resulting in 4×3×2×1=24 different combinations.
