The explanation given is not clear. If we want to draw an arrow starting at "a" and connecting to "a", then it means we need to move in the same direction and the answer remains the same, i.e., "a".
However, if we want to draw an arrow starting at "a" and connecting to "-a", then it indicates moving in the negative direction. In this case, the answer would be -a or -7, as mentioned in the explanation.
