 # Multi-Digit Multiplication 2

Directions: Using the digits 0 to 9 at most one time each, place a digit in each box to create a true equation with the greatest possible product. ### Hint

What two-digit numbers would be too low/high that when multiplied together would not make a three-digit product?

The greatest possible product found so far is 54 x 18 which equals 972 but there may be one even greater. Let us know in the comments what you find.
