Answer 1

To determine whether a situation represented a positive or a negative number, follow the addition and subtraction rules.

Step-by-step explanation:

To determine whether a situation represented a positive or a negative number, we follow some rules:

1. When two positive numbers add, the answer has a positive sign, e.g., 3+2 = 5.
2. When two negative numbers add, the answer has a negative sign, e.g., -4 + (-2) = -6.
3. When two numbers with opposite signs add, we subtract the smaller number from the larger number, and the answer has the sign of the larger number, e.g., -5 +3 = -2.
4. For subtraction, change the sign of the subtracted number and then follow the addition rules, e.g., 5 - 3 = 5 + (-3) = 2.

Let's use an example. Subtract -6 from 2: 2 - (-6) = 2 + 6 = 8.
