The American Mathematical Monthly is a peer-reviewed scientific journal of mathematics. It was established by Benjamin Finkel in 1894 and is published by Taylor & Francis on behalf of the Mathematical Association of America. It is an expository journal intended for a wide audience of mathematicians, from undergraduate students to research professionals. Articles are chosen on the basis of their broad interest and reviewed and edited for quality of exposition as well as content. The editor-in-chief is Annalisa Crannell. The journal gives the Lester R. Ford Award annually to "authors of articles of expository excellence" published in the journal.
The following persons are or have been editor-in-chief:
Ever since its founding in 1894 the American Mathematical Monthly has invited readers to propose and solve challenging mathematical problems for publication in its Problems and Solutions section. As of 2025 more than 12,000 problem proposals have appeared.

The table below lists solutions based on the following premise: something was published that justifies excluding the problem proposal from a list of unsolved problems.
For example, Calculus 360 ("solution" 1918 no. 4) is a question whose answer has no truth value and is thus "unsolvable" in a certain sense, so a mere reply to the question qualifies as a solution in the table.
In 1918 no. 5 a "note" on Calculus 435 also counts as a solution because the author refers to a paper then concludes: "To solve [problem 435] we need only put alpha = 0 in the first of the integrals mentioned." (However, since 435 has a solution in the previous issue, this note was omitted from the table.)
The "note" on 3064 in 1925 No. 1 counts as a solution because it points out that no solution exists to the problem as stated. Same for 3110 in 1925 No. 8 and 2706 in 1926 No. 2. (the presence of "Also solved by" is sometimes a tipoff to this scenario).
The only year in which the Monthly was true to its name was 1894, when 12 issues were published. Single issues for JulyâÂÂAugust and SeptemberâÂÂOctober appeared in 1895, and in 1896 JuneâÂÂJuly and AugustâÂÂSeptember were each single issues, launching the modern format (the modern issue-numbering scheme from 1 to 10 did not begin until 1913 however).
