5) sign
6) same

Answer 1

To subtract integers, the rule is 'keep, change, change,' which means keep the first number as it is, change the subtraction sign to addition, and change the sign of the second number before adding them together.

Step-by-step explanation:

To subtract integers, use the rule: keep, change, change.

The complete rule is to first 'keep' the first number as it is, 'change' the subtraction sign to an addition sign, and then 'change' the sign of the second number (the one being subtracted) to its opposite. After applying these steps, you follow the regular rules for addition.

For example, to subtract -6 from 2, you would follow these steps:

1. Keep the first number: (2)
2. Change subtraction to addition: 2 - (-6) becomes 2 +
3. Change the sign of the second number: 2 + (6)
4. Then add the numbers: 2 + 6 = 8
