- 17:08, 22 November 2019 (diff | hist) . . (+56) . . 2019 AMC 8 Problems/Problem 20 (condense solutions 1 and 2 to a more complete solution. Simply stating that the equation is quartic is not sufficient to show there are 4 real solutions.)

- 04:04, 22 November 2019 (diff | hist) . . (-109) . . 2019 AMC 8 Problems/Problem 20 (Solution 2 is incorrect as the fact that it is a quartic does not imply all 4 solutions are real.)

- 15:08, 30 May 2019 (diff | hist) . . (-346) . . 2017 AMC 10A Problems/Problem 25 (solution 4 is incorrect, since not every multiple of 11 has at most 3 permutations (e.g. 132 has six))
