Absolutely! Let’s solve each of the 25 problems step by step. We’ll use basic rules for working with negative numbers:
-
Adding a positive number → move right on the number line.
-
Adding a negative number (or subtracting a positive) → move left on the number line.
-
Subtracting a negative number → same as adding a positive (not needed here).
- When adding two numbers with different signs, subtract the smaller absolute value from the larger and keep the sign of the larger.
