Question 46264
<pre><font size = 5><b>I have to show my work with this problem- can you show 
me how to do it rather than just give me the answer so 
I do the others in the book, please? 
Simplify: 
-[-(-1)15] 
Thank you!


Do it from the "inside out":

-[<font color = "red">-(-1)</font>15]

Replace the <font color = "red">-(-1)</font> by <font color = "blue">(+1)</font>

-[<font color="blue">(+1)</font>15]

Replace the <font color="blue">(+1)</font>15 by <font color = "orange">15</font>

-[<font color = "orange">15</font>]

Remove the brackets and get

-15
