According to the above analysis, we can see that e can't be 0, otherwise B is also 0, which is not the meaning of the problem. Then we can see that f and G can't be 0, or 1; F and G can only be 2, 3, 4, 5 or 6. Considering that e ≠ 0, and excluding the case of repeated numbers, the number filling method satisfying formula 2 is only 3 × 4 = 12
