4 Digit Smallest Number- Let’s Know it Better!

Digits are the single symbols used to address numbers in Math. Let's take an example, in numbers 89, 8, and 9 are two digits. Hence, the numerals like 0, 1, 2, 3, 4, 5, 6, 7, 8, and, 9, are the type of digits that are used to address a combination of numbers and do arithmetic tasks in our everyday life. For example, OTPs that we receive, passwords, pins, etc.

Digits

The term digits are generally used in computer science. In mathematics, these digits are supposed to be mathematical or, in some cases, simply numbers. The smallest one-digit number is 1 and the most significant one-digit number is 9.

What is the Smallest 4 Digit Number?

The smallest 4-digit number is 1000. The smallest 4-digit number in the number system is 1000 since, in such a case that 1 is subtracted from the number it becomes a 3-digit number which is 999 (greatest three-digit number). So, we 1000 is the smallest 4-digit number in the number system.

Thus, the smallest four-digit number in the number system= 1000

= 1000 - 1

= 999 (which is the greatest 3-digit number)

So, 1000 is the smallest four-digit number.

What is the Smallest 4 Digit Odd Number?

The smallest 4-digit odd number in the number system is 1001. As we know that in the number system the smallest four-digit number is 1000 which is an even number, So we need to find the smallest four-digit odd number.

So, if we observe 1000 is an even number and 1000 - 1 = 999, which is a three-digit number, we need to see by adding 1 to 1000, Let’s see

Here, 1000 + 1 = 1001, we can see that 1001 is a four-digit number, the smallest after 1000 as well as an odd number which we are looking for.

So, here we proved that 1001 is the smallest four-digit odd number.

What is the Smallest 4 Digit Even Number?

The smallest 4-digit even number in the number system is 1000. Earlier, we saw that in the number system the smallest four-digit number is 1000 which is an even number, So if we look at how 1000 is the smallest 4 digit even number we find that,

1000 is an even number and 1000 - 1 = 999, which is a three-digit number and an odd number, so if we add 1 to 1000 it becomes an odd number and greater than 1000.

Here, we can see that 1001 is a four-digit odd number but 1000 is the smallest 4-digit even number.
