Yesterday, I answered this question (later deleted, see below for the text) and was a little surprised when the question was closed. A user in the comments stated, "This is not mathematics. It is arithmetic. Voting to close." The question was eventually closed. However, Wikipedia defines arithmetic as
a branch of mathematics that consists of the study of numbers, especially the properties of the traditional operations on them.
Furthermore, the FAQ states, "Mathematics - Stack Exchange is for people studying mathematics at any level and professionals in related fields."
This meta post also seems to come to a consensus that arithmetic questions are allowed on the site. And finally, the original question was not just arithmetic—it was dimensional analysis, which can get pretty tricky in certain circumstances. So can questions about arithmetic be answered on the site?
The question that is discussed
Title: Say, hypothetically, there were 4 seconds in 1 minute instead of 60 seconds. How many seconds would 24 hours (1 day) be?
Let 1 minute = 4 seconds.
Let 1 hour = 60 minutes.
Let 1 day = 24 Hours.
How many seconds would be in 1 day?
