{ Meet the arithmetic operations on integers.
  
  1. Run this program a few times with different
  integers to see what results you get.  What
  do the operators +, -, *, div, and mod compute?
  (These answers will not be surprising, so don't
  expect this to be a difficult exercise.)
  
  2. There is another operator, denoted by a slash
  (/).  What operation do think this represents?
  What happens if you try doing for / what we've
  done here for these other operations?
  
  3. Once you've seen what / does, try changing the type
  of a and b from "integer" to "real" and see what
  happens with / now.

program arithmetic(input,output);

var	a, b : integer;

begin
	write( 'Please type two integers separated by a space: ' );
	readln( a, b );
	
	writeln( a, ' + ', b, ' = ', a + b );
	writeln( a, ' - ', b, ' = ', a - b );
	writeln( a, ' * ', b, ' = ', a * b );
	writeln( a, ' div ', b, ' = ', a div b );
	writeln( a, ' mod ', b, ' = ', a mod b )
end.
