E7. Calculate the expansion of this 26 term expression:
E = (x - a)(x - b)(x - c)(x- d)\ldots(x- y)(x - z)

You want the whole thing? That's going to take up the whole board.
x^26 + (a+b+...+z)x^25 + (ab + ac +.. az + bc + bd +... yz)x^24 +... + abcdefghijklmnopqrstuvwxyz

God damn you, using the entire alphabet.
(x-x) = 0, so the whole thing is 0.
