I have 9 digits. My ten millions digit is a 0 and is 8 less than my hundreds digit. My hundred millions digit is 1 less than my thousands digit, 8 more than my millions digit, twice my ten thousands digit, and 4 times my hundred thousand digit. My digits in the ones period are zeros. What number am I?

If your school subject is St. Kylins, why does this look like a math problem?

My digits in the ones period are zeros.

xxx,xxx,000

now what else do you know?

To find the number, we need to use the information provided to determine the values of each digit.

We know that the ten millions digit is 0, so the number must start with a 0.

The ten millions digit is also 8 less than the hundreds digit. Since the only digit that can be 8 less than the hundreds digit is 8 itself, we can determine that the hundreds digit is 8.

The hundred millions digit is 1 less than the thousands digit. Since the digits in the ones period are zeros, the thousands digit must be zero. This means that the hundred millions digit is 0 - 1 = -1.

Now we can use the information about the hundred millions digit to determine the values of the other digits:

- The hundred millions digit is 8 more than the millions digit. So the millions digit must be -1 - 8 = -9.
- The hundred millions digit is twice the ten thousands digit. So the ten thousands digit must be -1 ÷ 2 = -0.5 (which is not a valid digit as it should be a whole number).
- The hundred millions digit is 4 times the hundred thousands digit. So the hundred thousands digit must be -1 ÷ 4 = -0.25 (also not a valid digit).

Therefore, it is not possible to find a valid number that satisfies all the given conditions.
