" expr generally works on "integers" as defined by the system. ie, once you
" hit MAX_INT weird stuff will happen.
" 
" If you want unlimited precision math, use bc

or, in ksh, $(( )):

print $((90 * 1000000000))

works fine.  and of course for you douglas adams fans,

typeset -i13 ANS=$((6*9))
print "the ultimate answer to life, the universe, and everything is... ${ANS#13#}"
