### Re: Cube it!

456^2+384^2+280^2+72^2=438976 = 76^3

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.

97^3 = 912673, and the digit sum of the difference between the answer and its reverse is 3^3.

Also, the difference between 3^3 and the reverse of the difference between 3^3 and its reverse is 3^3.

Note: The result of "the difference between" is an absolute value.
