Could you be a bit more precise where you _exactly_ see the problem,
please? "Several" does not help a bash n00b like me. Do you mean the '$'
is missing for example for 'SECONDS'?

If so, that isn't a problem:
----------8<----------8<----------
#!/bin/bash

FOO=42
BAR=23

echo $(( FOO - BAR ))
----------8<----------8<----------

Which will echo 19...
