Abstract
By using a result of L. Rudolph concerning the four-genus of a classical knot, we calculate the unknotting numbers of knots. We give an example of an infinite family of two-bridge knots which have arbitrary unknotting numbers which are equal to their three-genera. We also calculate the unknotting numbers of 10145, 10154 and 10161.
