Answer
Key
Problem solving
1 Among the given numbers , , , and , when , the equation
has the greatest product.
Julie: 82 73 5986
Dan: 92 64 5888
Therefore, Julie can make a greater product.
2 The greatest product can be made from the product of a (2-digit number) (2-digit number).
Therefore, the smallest product is made from the product of a (3-digit number) (1-digit
number). First, use the smallest number as the 1-digit number. Then, use the remaining three
numbers to make the smallest product.
Therefore, the smallest product that can be made is 256 1 256.
