Bash may be able to calculate, but it's just not the right tool. :)

'bc' should be available on all Unices:
user at host:~ > echo '((900*1000)/(25*(640*480)/(16*16)))' | bc # caution, no precision!
30
user at host:~ > echo '((900*1000)/(25*(640*480)/(16*16)))' | bc -l
30.00000000000000000000

Sorry for OT,
Moritz

P.S.: I use calc, which is much more capable and usable than bc.
