-1. What is the out put of the following code::
+1. Obtain the sum of primes between 1 million and 2 million. 
+
+   Answer::
 
-     c1 = Combinations([1, 2, 3, 4])
-     c2 = Combinations([1, 2, 4, 3])

-     l1 = c1.list()
-     l2 = c2.list()

-     for i in l2:
-         l1.remove(i)
+2. ``graphs.WorldMap()`` gives the world map in the form of a
+   graph. ::
 
-     print l2

 To find the limit from the negative side, we say,

 Let us now see how to differentiate, using Sage. We shall find the
 differential of the expression ``exp(sin(x^2))/x`` w.r.t ``x``. We
