    I just realize that my $30/US$25 Casio fx-991ES calculator can do integration, differentiation, complex number calculation, and a lot of other stuff, and the battery last for ages, what a good deal!!:eek:

    I keep finding scientific calculators like TI-30-II series for $3.99 at thrift stores. Usually just need batteries...that jacks up the cost. ;)
