Every letter A-Z and every number 0-9 is contained in the boxes below. Each box contains exactly one letter or number. Adjacent includes diagonals. Neither 0 nor 1 is a prime number. 0 is divisible by every whole number. When a clue mentions whether a letter is comprised of curves and/or straight lines, it is referring to the capital form of that letter. Letters that are considered to have both straight lines and curves are B, D, G, J, P, Q, R, and U. Letters with only curves are C, O, and S. Y is considered to be a consonant, and not a vowel, for the purposes of this quiz. The name for the number 0 is 'zero'.
