Using Algebrator 7 Selecting, copying, cutting and pasting sub-expressions These operations can be done with standard mouse click-and-drag as well as with arrow key combinations. Note that cutting ‘across’ expressions such as will produce an extra space holder which is generally not desirable: Here, a press of either the backspace or delete keys will remove the extra space-holder. Space-holders and editing When you enter an expression such as: delete b and decide to move to another part of the expression: the algebraic editor will insert a space-holder in place of b. You will have to ‘resolve’ that space-holder before being able to solve the problem (either by entering something in its place, or by deleting it). Note that deleting the spaceholder in this particular case will actually delete the fraction and replace it by its former numerator (a).
