One thing you might try is using the double parens math workings of bash. Quite cool and is readable, and it avoids your shell expansion problem. Secondarily, a "here" document with the "dc" program is how I used to do it. e.g.:

dc <<EOF
2 20 * p
EOF
will produce 40 as output

Using the double-parens syntax of bash, one can do this:

$i=0
((i=2*20))
echo $i <-- produces 40

Kinda cool, huh?
