It is negative because:

$\displaystyle -\frac{21}{24} + \frac{20}{24} = \frac{-21 + 20}{24} = -\frac{1}{24}$

No problem. I have a video of my own where I demonstrate how to add two fractions, even if the denominators happen to be different: https://www.youtube.com/watch?v=ywycowKlgDg

Okay, I have a question can I skip arithmetic and jump to algebra 1? Will you use this kind of fractions on it? Would you still do some lowest terms in algebra 1??

I suppose you could, but considering you wanted to multiply instead of subtract in your original problem I'd stick with the Arithmetic for a while longer.

Math Focus: Calculus
negative negative product becomes positive and then you subtract 7/8 from 5/6, since 7/8 is bigger number so you get negative result.
