Note
A regular plural made with a plain -s, and it belongs mostly to the countable meanings of equation. Each statement of equality written around an equal sign counts as one, so a problem may call for a set of equations. The small corrections applied to observed values to remove systematic error are counted the same way. The act or state of equating, by contrast, is a process and seldom takes a plural.
