The singular was &quot;thou / thee / thy /thine&quot; </p><p>The formal &quot;you&quot; became informal and replaced the singular.&nbsp; The nominative &quot;ye&quot; also disappeared. <br /></p><p>Now, informally, there are several expressions - y&#39;all (you all), youse (from Irish) <br />http://www.englishforums.com/English/OneAndOne/jvqw/post.htm#45653Wed, 15 Sep 2004 07:13:46 GMT946f00bb-57d3-4b7b-a9a2-059b5341af52:45653CalifJimWhen it comes to mathematical equality, the underlying idea is that one quantity equals another. <br /> <br />4 + 5 + 1 = 10 <br /> <br />(The quantity) four plus five plus one equals (the quantity) ten. <br />Four and five and one equals ten. <br /> <br />One and one is two. <br /> <br />From a strict grammatical point of view, a plural subject (one and one) requires a plural verb (equal or are), but many people feel more a sense that the unstated word "quantity" is the subject and so requires a singular verb. <br /> <br />In short, either one, in my opinion, is acceptable. <br /> <br />If the context is completely mathematical the equal sign (=) is normally read "equals", no matter what numbers or mathematical expressions are to the right or the left of the equal sign.
