Use the "array processing" inherent in functions such as Plus and Times that have the attribute of being Listable , namely: C = A - (1/2)B That's it! (You can do Simplify later. And even there, you don't need to do any explicit indexing, but -- at least for a one-dimensional list -- just use Map: Simplify/@C On 4/10/2010 6:52 AM, John Ertle Jr. wrote: > I want to subtract array A by 1/2 array B and put it in array C.
