Because your version takes up 6 lines! A simple one line expression!<p>And yes you can remove the parentheses, but not only does no one do that, it still takes up 6 lines. And then you have significant whitespace too.<p>&gt;why do you insist on using infix syntax for a couple of operators, while you use every other possible operator in a prefix notation and are happy with it? What is the difference between &quot;sqrt&quot; and &quot;-&quot; which makes it ok to use sqrt in prefix form?<p>Because that&#x27;s universal and standard for math notation. But also sqrt only takes one argument. If it took two arguments, then it would be perfectly reasonable to add an infix operator for it too. Many languages do add infix operators for everything from combining strings to ANDing booleans, etc, because they are so much more readable.
