Answer 2

Comparison of Examples and Rule Identification

Let's compare the examples provided in each column and try to identify the rule based on which they are arranged.

Column 1: 9-6, 9-5, 9-4, 3+6, 3+5, 3+4, 8-3+4, 8-2+3, 8-1+2, 6+4-7, 6+3-7, 6+2-7

Column 2: 7+2, 9-5, 6+3, 8-6, 36-4, 42+6, 78-40, 37+20, 8+9, 6+8, 7+6, 4+7

Column 3: 875-528, 900-547, 906-547, 1000-456, 567-209, 684-406, 395-107, 478-89, 234-65, 356-78, 538-229, 465-156, 644-335

Based on the examples, we can observe the following rules:

1. In Column 1, the numbers are arranged in a pattern where subtraction and addition operations alternate. The first number is always 9, followed by a subtraction operation, then a number from 6 to 4, then an addition operation, and so on.

2. In Column 2, the numbers are arranged in a pattern where addition and subtraction operations alternate. The first number is always 7, followed by an addition operation, then a number from 2 to 6, then a subtraction operation, and so on.

3. In Column 3, the numbers are arranged in a pattern where subtraction operations are performed between larger numbers and smaller numbers. The first number is always larger than the second number, and the result is obtained by subtracting the second number from the first number.

Let's calculate one more example based on these rules:

Example: 6+2-5

According to the rules identified, we can calculate this example as follows:

6 + 2 - 5 = 8 - 5 = 3

Therefore, the result of 6+2-5 is 3.
