Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have:

[tex] \frac{a}{b+a+s} + \frac{c*b}{(b+a+s)(c+s)}[/tex]

I can rearrange that to:

[tex]\frac{a-c}{b+a-c} * \frac{b+a}{b+a+s} + \frac{b}{b+a-c} * \frac{c}{c+s} [/tex]

Is this correct? If so, can someone tell me why the +s changes into a -c?
