how can I caculate with numbers bigger than a word using 16F88 ?

I'm trying to rid the world of 16F chips...

I'm with you, Charles, but is there a PIC18 that is nearly the same price as a PIC16F88? I'm doing a low cost consumer product right now where 40 cents makes a big difference. Until that time, that evil PIC16F architecture lives on.
