If you notice an input mistake before you press the arithmetic operation key, simply press
to clear the value and enter it again.
In a series of calculations, you can correct errors in intermediate results by recalculating
correctly when the error appears and then continuing with the original series from where
you interrupted it.
If you make a mistake by pressing the wrong key when entering ci Q, Q. Q, Qx or
xk, simply press the appropriate key to correct. In this case, the most recently pressed
key operation is used, but it retains the order of precedence of the original operation
entered.
