To move (a term) from one side of an algebraic equation to the other side by addition or subtraction which causes its sign to change.
terms are separated by + and - signs.
Example:  solve 2x+3=9                         2x+3-3=9-3 (subtract 3 from both sides)                         2x=9-3          (the 3 has been TRANSPOSED to the RHS)                         2x=6                         x=3
