How many six-digit numbers are there in total?

by

A six-digit number is defined as any integer that falls within the range from 100000 to 999999. These numbers start from 100000 and continue all the way up to 999999, inclusive.

To find the total number of six-digit numbers, we can use a simple calculation:

  • The smallest six-digit number is 100000.
  • The largest six-digit number is 999999.

Now, we calculate the total count by subtracting the smallest number from the largest and then adding one (to include both endpoints in our count):

Total 6-digit numbers = 999999 - 100000 + 1
                    = 899999 + 1
                    = 900000

Thus, there are 900,000 six-digit numbers in total.
