108. (x+y)(z+w)(x-y)(z-w) will have 4 terms

reason: recognize the difference of the squares (x^2-y^2) and (z^2-w^2), when we multiply them we get 4 terms

Another simple question hiding behind the words "Challenge Problem." What's so challenging about it? College Professors love showing off how much they know or think they know. Wrong choice in words by Sullivan. Agree?

challenging about it is to recognize the difference of the squares not all students would see that at first glance
