This is a problem about number filling. We need to find the right number to fill the blank position, so that the equation can be established.
First of all, we can observe that there are two brackets in the equation, and we need to calculate these two brackets separately.
For the first bracket 6s5, we can try to add the numbers 6 and 5 to get 1 1, and then subtract 5 from1to get 6, so the result in the first bracket is 6.
For the second brackets 23 and 272, we can try to add the numbers 2 and 7 to get 9, and then subtract 2 from 9 to get 7, so the result in the second bracket is 7.
Now we have got two results, 6 and 7 respectively.
Next, we need to combine these two results into a new number.
We can add the numbers 6 and 7 to get 13, and then subtract 6 from 13 to get 7, so the combination result is 7.
Then, after filling in the appropriate numbers, the equation becomes: (6+5)-5=(2+7)-2, and the answer is: 7.
