Open Middle®
Directions: Using the digits 0 through 9, at most one time each, place a digit in each box to create the greatest possible value.
Hint
How do the order of operations tell you what you should do first? What possible values can you make on the left/right side of the equals sign? Which side would it be better to start with?
Answer
The greatest possible value for both sides of the equal sign is 76 which comes from a few possibilities including 76 ÷ (3 – 2) = 4 + 9 x 8.
