I am going to be taking an advanced course in computer architecture soon and we are aloud to have a calculator or software to do all of the computations. I know there is math cad, but it is to expensive.

Is there any freeware or something that can handle the following:

1. find the sign, carry, and zero flag bits.
2. binary to (unsigned,signed,ascii,bcd).
3. decimal to floating point.
4. decimal to hex.
5. whole number to excess 3.
6. Hex to decimal.
7. find the two's complement of a binary number
8. BCD addition.

Any help on some software or calculator that can do this would be great.
