How many 4-digit numbers are there in all?

Asked by Topperlearning User 17th April 2014, 1:34 PM
Answered by Expert
Answer:

The largest 4-digit number = 9999

The smallest 4-digit number = 1000

Number of all 4-digit numbers = (9999 - 1000) + 1

                                           = (8999 + 1)

                                           = 9000
