For a trial we expect more along the lines of what you showed in that image - a calculator. Although encoders or decoders (binary to display stuff) are important, they take too much time to build on trial. Generally we require someone to build a ALU (arithmetic & logic ops) you can also choose to make a multiplier / divider or anything of the same difficulty.
