The first number has to be 1 smaller than the fourth, then take the fourth number away from 10 and the number that you are left with should fill the second and third place.

Examples:

2 7
7 3
27 + 73=100
27 + 73=100

100 + 100=200

3 6
6 4
36 + 64=100
36 + 64=100

100 + 100 = 200

0 9
9 1
09 + 91=100
09 + 91=100

100 + 100 = 200

4 5
5 5
45 + 55=100
45 + 55=100

100 + 100 = 200

5 4
4 6
54 + 46=100
54 + 46=100

100 + 100 = 200

6 3
3 7
