Subtraction

Nature can be expressed in terms of math 'Tis full of quantities and relations Bounded by the law of interactions Endpoint implies our dream; segment, our path There are as many symbols that replace As there are things in this wonderful place A plus signifies accumulation Of things we desire and of friends we need Constancy of amount of which will lead To a process called multiplication A plus is the most legal for the mind 'Cause it never keeps anything behind But everything has to undergo change We're bound by this law of the universe That we can see a thing and its reverse Just as a domain produces its range Our gaining results another's losing Hating this we'll find us violating Nature is as compliant as we are We have a minus which means subtraction Of something from our accumulation Like seeing true friends going home afar For memory 'tis the most illegal Putting this sign between minds is lethal To Eric and Michael
