CAN YOU
MULTIPLY?
Using the digits 1, 2, 3, 4, 5, 6, 7, 8, and 9 only once, what are the two numbers which multiply to give the largest product? To clarify, the solution might be 7463 times 98512, which uses the nine digits only once, but it isn't because there is a pair fulfilling the conditions which gives a greater product than those two.
