Let the VHDL compiler make it for you.

...

signal a:integer range 0 to 7:=5 ;
signal b:integer range 0 to 7:=6;

signal c:integer range 0 to 16 :=7;

signal result : integer range 0 to 127;
...

begin

  Timer: process (Clock_50MHz) is begin

    if rising_edge(Clock_50MHZ) then
       result <= a*b+c;
       a      <= a -1;
    end if;

  end process;
...

Why do you not check it out? Enter your code and let quartus synthesize 
it!

Where ist the problem to test it out?

Show what you have and report whats the problem with it. Then someone 
might help you, but we intend not to do your homework completely...
