EEExxxeeerrrccciiissseee There is only one space next to 5 6 , so the only number that fits in the blank is
6. Also, 3 1 is 3= +1, so the number that fits in the blank is 2.
Use this method to fill in the remaining spaces.

EEExxxeeerrrccciiissseee The expression that fits in the vertical line is 17-8=9 and 17-9=8.
The expression that fits in the horizontal line is 7+8=15. The common
number that overlaps both expressions is 8.

7 + 8 = 15

6=3+2+1, so the numbers that fits in A, B, and C are 1, 2, and 3.
The sum of the numbers of D and A, and of C and E is 9. Numbers from 1 to 7
are used only once. The pair of numbers that fit are (2, 7) and (3, 6). So, B is 1.
Fill in the remaining numbers using the same method.
