Operations Grid Task

Find the highest possible grand total by placing the numbers 1 to 9 in the empty cells in the grid, performing the operations, and adding the results together. You must use each of the numbers exactly once.

Work for ten minutes on your own, then work with a partner for another ten minutes to see if you can improve your score.
