How many 6-digit number combinations are there?

The smallest 6-digit number is 100,000 .
The largest 6-digit number is 999,999 .
If you count from the smallest one to the largest one, you'll name every possible one.
But that's exactly the same thing as counting from 1 to 999,999 except skipping the first 99,999 because they don't have enough digits.
So you're left with (999,999 minus 99,999) = 900,000 numbers remaining

999999 × 2 if you want to include the negatives

There are 900,000 different 6-digit number combinations, ranging from 100,000 to 999,999. This is calculated by subtracting the smallest 6-digit number (100,000) from the largest (999,999) and adding one. Hence, the calculation yields a total of 900,000.
