Development and Application of the Problem on an Equation

In the mathematics teaching of the middle school, adopting changing one problem into diverse forms can excite student's latent ability, improve student's synthetic quality, this is essential to bringing up the creative talent. Application changing one problem into diverse forms contains solving one problem by different methods, too. Changing one problem into diverse forms can realize the deep understanding to the content of courses and grasping it in all-sides and bring it together and understand thoroughly by the continuous development, amplification of the same problem.
