Can you divide numbers from 1 to 9 (1 2 3 4 5 6 7 8 9) into two groups so that sum of the numbers of each group is equal?
Note: 9 cannot be turned over to make it 6.
1 2 3 4 5 9 and 7 8 9
sum of numbers 1 2 3 4 5 6 7 8 9 is 45 , so numbers cant be split into 2 equal parts.
I know i cant turn 9 upside down and make it 6 but i can turn 6 to make it 9.
