Correcting Errors Correcting Entry Errors - (Clear Entry/Clear)-To clear a numerical entry, press - once; then enter the correct number. To clear all pending operations and begin the calculation again, press - twice. w (x Exchange y)-Exchanges the values of x and y. If you enter x and y in the incorrect order, press w to reverse them. Then complete the calculation. v (Backspace)-Removes the last digit or decimal point from the displayed number if you have not yet pressed an operation key (p, o, n, m, etc.). This key is useful for correcting entry errors without having to clear the display and start again. Correcting Immediate Functions You can often correct an immediate function by performing the "reverse" operation. For example, if you press 0 ] by mistake, you can correct the operation by pressing 0 k. 7
