On the other hand, will graphics problem into the algebra problem, in order to obtain the accurate conclusions. Improve the analysis and problem solving ability so as to achieve simple problem solving method, the final convenient our problem solving. I will from the following several aspects to discuss several form combining ideas middle school mathematics in the application: (1) the application of the set; (2) in the process of the application of the solution; (3)the application of inequality in solution; (4)in the application of analytic geometry; (5)to solve the most value, domain in its application. Through the analysis, comparison and induction show several form combining ideas of problem in the characteristic and advantages, which in actual teaching will form together with several ideas to the classroom, training students strengthen the consciousness of combining ideas number form. 【Key words】 Middle school mathematics Several form combined with An applicati
