I found one solution: 2 + 566 + 190 = 758.
The next two are Tiger's solutions:
1) 789 + 266 = 1055
2) 965 + 725 = 1680
Wishing everyone a very Merry Christmas and a Happy New Year!
I hope all of you have a restful time with your friends and family, and we shall see you back here in the new year refreshed and ready to go!
