Open Middle®
Directions: Using the digits 0 to 9, at most one time each, place a digit in each box to find an odd modulus, an even modulus, and the smallest possible modulus.
Hint
Consider Pythagorean Triples.
Answer
|(3+8i) + (6+4i)| = 15
|(7+8i) + (9+4i)| = 20
|(1+2i) + (5+6i)| = 10
|(7+8i) + (9+4i)| = 20
|(1+2i) + (5+6i)| = 10

|(5 + 4i) + (0 + 8i)| = 13.
Consider removing the third solution as the number 1 is used twice.
