Running awk to process two lines is severe overkill. It's like making a telephone call to speak two words. If you do this a lot in shell scripts, they're going to be very slow and inefficient.

Or are you writing large things in pure awk?

If the latter, you can incorporate this into part of a larger awk statement more easily:

Code:
awk 'BEGIN {
...
        getline VAR1 <"filename1"
        getline VAR2 <"filename2"
        printf("%d+%d=%d\n", VAR1, VAR2, VAR1+VAR2);
...
}'
