Crack elimination is one of the most important ways to sum up series in high school mathematics. The series summation and serial inequality problems associated with the split-phase elimination method often appear in college entrance examination and mock examinations. In order to help students better To master the split-phase method, cited the entrance exam or simulated test of some typical questions (especially in order to highlight the problem of the split-phase method to solve the problem, nothing to do with the solution to readers. Type 1 The difference between the denominator and the numerator has divided the general line of the series into two, the common fission
