In first order logic, I have read that there are a couple of identity rules and I have a question for example: If you have "a=b" does it mean that I can also write it as "b=a"? Is it true the one-way or both? And if I have two statements such as "a=b" and "a=c". Can I derive both "b=c" or "c=b" from this?

• If I have "a=b" does it mean that I can also write it as "b=a"?
• Is it true one-way or both?
• And if I have two statements such as "a=b" and "a=c". Can I derive both "b=c" or "c=b" from this?
