Size indicator is how many of what you are counting to make a whole 1 of something.

We need to add/subtract counts but we can only do this 'directly' if the 'size indicators' (denominators) are the same.

Change the order:

This is the same in value as:

To add ( -\frac{9}{8} + \frac{7}{4} ), you need to find a common denominator, which in this case is 8. Then, you can add the numerators together. So, it becomes:

(-\frac{9}{8} + \frac{7}{4} = -\frac{9}{8} + \frac{14}{8} = \frac{-9 + 14}{8} = \frac{5}{8}).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
