We can start by assigning a numerical value to each letter in the phrase "LOKI + IDUN + ODIN = THOR" as follows:
L = 3 O = 6 K = 2 I = 9 D = 5 U = 7 N = 1
So the equation becomes:
3 + 6 + 2 = 12 = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9
Therefore, one possible solution to the equation is 362. However, since there are six possible solutions, we can try another combination of letters:
F = 6 E = 5 A = 1 D = 5 U = 7 R = 2
So the equation becomes:
6 + 5 + 1 = 12 = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9
Therefore, another possible solution to the equation is 651.
