This is often used on blackboards, so this is a good place to talk about whether to reverse what's on the blackboard or not. It certainly is not necessary to represent equations from the signer's right to the signer's left (unless the interpreter is left-handed), as if Deaf people were not used to reading fingerspelling from the signer's perspective. If the interpreter is representing a visual such as a drawing on the blackboard or an overhead, the interpreter should "reverse" their drawing so that if for example an inclined plane slopes form the audience's left to their right, the interpreter makes it slope from their left to their right also (which would be from the interpreter's right to his/her left). In this situation, the interpreter might turn slightly to emphasize that it is coming out of the blackboard behind and the interpreter is not doing it from his/her perspective.
