5) -8

Answer 3

Let's solve the expressions one by one:

1. (-2) + (-5) When adding two negative numbers, you can simply add their magnitudes and keep the negative sign. Therefore, (-2) + (-5) equals -7.

2. (-6) + (-4) Similar to the previous example, when adding two negative numbers, you add their magnitudes and retain the negative sign. So, (-6) + (-4) equals -10.

3. (-2,3) + (-4,5) It seems like you have provided values in a coordinate format. To add two coordinates, you add their corresponding components. Therefore, (-2,3) + (-4,5) would result in (-2 + -4, 3 + 5), which simplifies to (-6, 8).

4. (-0,5) + (-0,5) The addition of these two values can be simplified as (-0.5) + (-0.5) which equals -1.

5. (-8) + 0 When adding any number to 0, the sum will be equal to the number itself. Therefore, (-8) + 0 equals -8.

So, to summarize:

1. (-2) + (-5) = -7
2. (-6) + (-4) = -10
3. (-2,3) + (-4,5) = (-6, 8)
4. (-0,5) + (-0,5) = -1
5. (-8) + 0 = -8
