A partial answer is:
$ irb --prompt-mode xmp
1 + 2
     ==>3
5-3
     ==>2

For more information read man irb

As i see it, it is not possible to get the output on the line. Maybe 
also investigate the emacs xmp package.

Customizing prompt
        To costomize the prompt you set a variable

            IRB.conf[:PROMPT]

        For example, describe as follows in `.irbrc'.

            IRB.conf[:PROMPT][:MY_PROMPT] = { # name of prompt mode
              :PROMPT_I => nil,         # normal prompt
              :PROMPT_S => nil,         # prompt for continuated strings
              :PROMPT_C => nil,         # prompt for continuated statement
              :RETURN => "    ==>%s\n"       # format to return value
            }

        Then, invoke irb with the above prompt mode by

            $ irb1.8 --prompt my-prompt

        Or add the following in `.irbrc'.

            IRB.conf[:PROMPT_MODE] = :MY_PROMPT

        Constants PROMPT_I, PROMPT_S and PROMPT_C specifies the format. 
  In the prompt specification, some special strings are available.

            %N    command name which is running
            %m    to_s of main object (self)
            %M    inspect of main object (self)
            %l    type of string(", ', /, ]), `]' is inner %w[...]
            %NNi  indent level. NN is degits and means as same as 
printf("%NNd").
                  It can be ommited
            %NNn  line number.
            %%    %
        For instance, the default prompt mode is defined as follows: 
IRB.conf[:PROMPT_MODE][:DEFAULT] = {

        PROMPT_I => "%N(%m):%03n:%i> ",

        PROMPT_S => "%N(%m):%03n:%i%l ",

        PROMPT_C => "%N(%m):%03n:%i* ",

        RETURN => "%s\n"}
               RETURN is used to printf.
