D has the same answer. D has the same answer, because a means -14 + 8 which equals -6 which isn’t equal to the answer to the first one (-22). The next one you switch the - to a + and the -8 to 8 so it would equal 22. C equals -6 which also doesn’t equals the first one. So the last one is right because one you add to negative so still end up with a negative.
