Coded

Follow these directions:

Select any three digit number such that the hundreds digit is at least two greater than the units digit. (For example: 672) Call this number w.
Reverse the digits of w. (For example: 276) Call this number x.
Subtract x from w. Call this remainder y.
Reverse the digits of y. Call this number z.
Add y and z.
Multiply the sum of y and z by 100,000.
From the product obtained in the last step, subtract 8,685,432.

This number is the final answer. However, it is in code. To produce the message, substitute a letter for each digit according to the following key:

0 – o
1 – l
2 – f
3 – m
4 – i
5 – r
6 – p
7 – w
8 – a
9 – g

If your work is correct, you should be able to read the decoded message.
