To solve these equations, we can use the basic rules of addition and subtraction. Let's break down each equation and explain how to find the solution:
1. Negative 10 + 8 = Negative 2
To add negative numbers, you can follow these steps:
- Start with the first number, negative 10.
- Take the second number, positive 8.
- Add the numbers together, considering the signs: -10 + 8 = -2.
- The result is negative 2.
So, the correct answer is negative 2.
2. 9 - Negative 9 = 18
To subtract negative numbers, you can use the rule that states subtracting a negative number is the same as adding its positive counterpart. Follow these steps:
- Begin with the first number, 9.
- Subtract the second number, negative 9.
- Change the subtraction operation to addition: 9 + (+9).
- Apply the addition: 9 + 9 = 18.
- The result is 18.
So, the correct answer is 18.
