They should. Every published set of problems that I've ever solved by hand has. I went searching online for some, and found this page: http://puzzlepicnic.com/genre?alphametic which clearly states that exact restriction. The implication is that you're solving a puzzle in arithmetic (usually addition or long multiplication), and it is *exactly* as you would have written it with digits, save that the digits have been replaced with letters (and carries have been omitted, since that'd make it too easy). You wouldn't write a leading zero on a number in standard grade-school arithmetic, so you also won't use a leading zero in anything here.
