Specifically ∑

_{i}a

_{i}.10

^{i-|i|}in any form where I can work with ∑

_{i}a

_{i}= α and ∑

_{i}10

^{i-|i|}separately.

Is there a homomorphic function I can run it through such that ∑ab can be expressed as ∑a∑b? Note: for current problem i cannot simply set it up such that ∑a∑b - ∑ab polynomial expansion saves the day, any help appreciated.
