Some expressions not working

[ghost]

The expression 3×-(2+2) and -(2+2)+8×5 not working. Please fix this.

[uklimaschewski]

The expression 3-(2+2) is working and giving a result of -1.
The expression -(2+2)+85 is invalid. The - is not supported as a prefix operator.

I write 3×-(2+2) not understand why asterisk not appeared, and by the that i studied in mathematics a "-" before of a parentheses denies the result that is between he.

I am making a calculator for android, and your class is really perfect for me, and by account of this bug, i that use expressionString.replace("×-(", "×-1×("); what not is very nice.

I understand that and I'd like to have them, too, but unary operators are not supported at the moment, see issue #36.

The expression 5+5 (105+5, 255+5, 75+5 etc.)giving a result of 1E+1. Why?

@element111 use toPlainString(). See http://stackoverflow.com/questions/925232/why-does-java-bigdecimal-return-1e1
