Okay. What you do is write it out yourself. Do it like this:\[\frac{ -10 }{ -6 } = \frac{ -1 \times 2 \times 5 }{ -1 \times 2 \times 3 } = \frac{ 5 }{ 3 }\]Do you understand what I did?

Yeah. If you have a negative on both the top and the bottom mathematicians cancel them out. It's kind of because we're lazy - we don't like to write negatives everywhere if we can help it. :)
