Storing a constant If you enter the same operation more than twice consecutively, K disappears andreappears alternately with each additional entry. If you enter the same operation twice consecutively, K appears on the screen and the previous result is stored in a temporary memory. That result is automatically reused if you neglect to enter an operation before a number. Example: 5 + + (K appears and 5 is stored) 2 = gives 7. Then, press 3 = 8 is displayed. Clearing When an error occurs during calculation, -E- wilt appear. To delete this, clear the whole mathematical equation with A. C clears the last entered number or operation. Example: 1 + 2 C 3 gives 4 (2 has been cleared). To clear an operation and replace it with another, you may also enter the second operation. When you enter two or more different operations in a row, or only the last operation is used. Example: 1 * + 2 gives 3. A clears all operations and numbers.
