Answer 2

Answer:

Numbers are categorized according to the number of digits that they have and the place value of a number helps in understanding the value of each digit. The 4 digit number series begins with the number 1,000 and ends with the number 9,999. 4-digit numbers are the numbers having 4-digits and we can form 4-digit numbers by using any digits from 0-9, but the number should begin with digit 1 or a number greater than 1.

Tips and Tricks on Numbers up to 4-Digits

Given below are some of the tips and tricks on numbers up to 4 digits which can help while solving problems related to these numbers.

When any one-digit number (from 1 to 9) is multiplied by 1000, the resultant number is a 4-digit number. For example, 4 × 1000 = 4,000; 5 × 1000 = 5,000

When any two-digit number is multiplied by 100, the resultant number is a 4-digit number. For example, 44 × 100 = 4,400; 54 × 100 = 5,400

When any three-digit number is multiplied by 10, the resultant number is a 4-digit number. For example, 444 × 10 = 4,440; 678 × 10 = 6,780

When any four-digit number is multiplied by 1, the resultant number is a 4-digit number. For example, 4444 × 1 = 4,444; 2345 × 1 = 2345

The smallest four-digit number, using all different digits, is 1023.

The smallest four-digit number, using only one-digit is 1,111.

The smallest four-digit number, using two different digits is 1,000. (1,000 is the least four-digit number too).

The greatest four-digit number, using only one digit is 9,999 (9,999 is the greatest four-digit number too).

The greatest four-digit number, using two different digits is 9,998.

The greatest four-digit number, using all different digits is 9,876.
