+= is not valid syntax, and will not be accepted without correction.
=+ is valid, but =+A1+B1 is just the same as =A1+B1
Some people write the formula as +A1+B1 (without the = sign), but Excel will
interpret it as =A1+B1

Use of the + in such situations is a relic from old Lotus spreadsheet
applications.
