numbers); and/or (2) where appropriate, illustrate or annotate your thought process in some
way. But, be brief! (You need not use full sentences, etc.)

You need not carry units through your calculations, but you do need to tack appropriate units
onto your final answers, where necessary (i.e. for numeric answers).

For problems requiring symbolic answers in terms of specific variables, you may of course
include in your answer any necessary constants, numbers, and/or symbolic representations of
exact numbers. (For example: εo, e, me, 7, ln(7), e7, etc.)
