HP Prime Graphing NW280AAABA manual Using the clipboard, To reuse the last, Result

T i p	Pressing S=takes you straight to the very first entry
	in history, and pressing S\takes you straight to the
	most recent entry.
Using the clipboard
	Your last four expressions are always copied to the
	clipboard and can easily be retrieved by pressing
	SZ. This opens the clipboard from where you can
	quickly choose the one you want.
	Note that expressions and not results are available from
	the clipboard. Note too that the last four expressions
	remain on the clipboard even if you have cleared history.
To reuse the last	Press S+(Ans) to
result	retrieve your last answer
	for use in another
	calculation. Ans
	appears on the entry
	line. This is a shorthand for your last answer and it can be
	part of a new expression. You could now enter other
	components of a calculation—such as operators, number,
	variables, etc.—and create a new calculation.
T i p
	You don’t need to first select Ans before it can be part of
	a new calculation. If you press a binary operator key to
	begin a new calculation, Ans is automatically added to
	the entry line as the first component of the new
	calculation. For example, to multiply the last answer by
	13, you could enter S+s13E. But the
	first two keystrokes are unnecessary. All you need to enter
	is s13E.
	The variable Ans is always stored with full precision
	whereas the results in history will only have the precision
	determined by the current Number Format setting (see
	page 31). In other words, when you retrieve the number
	assigned to Ans, you get the result to its full precision; but
	when you retrieve a number from history, you get exactly
	what was displayed.
