To evaluate expressions with negative numbers, you simply add or subtract the numbers according to the signs. Here's how you can find the solution for the given expressions:
1. -20 + (-10): Start by adding the two negative numbers. "-20 + (-10)" is equivalent to "-20 - 10". Adding -20 and -10 gives -30, so the answer is -30.
2. -12 × 3: Multiply the two numbers. In this case, -12 multiplied by 3 equals -36. So, the answer is -36.
3. 87 + (-96): Add the two numbers. In this case, 87 added to -96 gives -9. So, the solution is -9.
4. 204 + (-36): Again, add the numbers. 204 added to -36 equals 168. Therefore, the solution is 168.
