Say we have:
$$\frac 12 + \frac 13 + \frac 14$$
When I calculate this on my TI-84 Plus CE-T, it gives
$$\frac {13}{12}$$
Instead of
$$1\frac {1}{12}$$
Is there any reason for it doing so and is this setting-related?

Why doesn't my Ti-84 simplify fractions

It's just how it's built in. In fact, you can change the output to give mixed numbers (I don't remember where). But as mentioned in comments, in general, mixed numbers really aren't preferred in any field of mathematics, but may be useful for the layperson in another field.
