Prove the 8 divisibility test for ANY number. This should be a mathematical proof, not a word or paragraph proof.    DO NOT write a proof that is for just a four-digit number or a five-digit number.  If you do that then you are not proving it for ANY number.  You must prove it for ANY number by proving that 8 | (10n-1an-1 + 10n-2an-2 + 10n-3an-3 + … + 100a2 + 10a1 + a0).   without modular
