When you start a new line in solving an equation (or any math problem), is there a symbol you should start of with? I usually use an equal or therefore sign but sometimes it doesn't seem appropriate and I just end up using a little arrow(adsbygoogle = window.adsbygoogle || []).push({});

Say I had to rearrange this equation (ab)/2 = c to make a the subject , what would I write in front of the first and subsequent lines of working? Just leave it blank?

e.g.

(ab)/2 = c

<--- what goes here? (ab) = 2c..etc.

etc..
