Video Summary

Anne aims to compute the largest possible result in the calculation K-A-N + G-A - R-O-O using numbers 1 to 9. The approach is to maximize K-A-N + G-A and minimize R-O-O. Assign 1 to the hundreds place in R-O-O, making it 122, and use 2 for the O's. Use 9 for the hundreds place in K-A-N, 8 for A, and 7 for G to maximize sums. Calculating gives two possible sums: 1064 and 1063. Subtracting 122 from the larger yields the maximum result of 942. Thus, the answer is D, 942.
