Java - calculating large mathematical expressions

I have to deal with a scenario when patients have to figure out some huge mathematical expressions. The expressions themselves are simple, i.e. They have only ordinary BODMAS fundamental ones, but the numbers that occur as operands are very large, with an accuracy of 1000 digits. I know the BigInteger class of the java.math module, but I'm looking for another way so that the calculation can take place in a quick way. Im a guy still finds his legs in java, so any pointers or advice in gthis would be a big help.

I am surprised that equations with 1000 digits have practical applications (with the possible exception of encryption) Could you explain what you are doing and what are your speed requirements?
