mr / all
Call up the contents of the memory. Press and hold to display the calculation history page that recorded all calculation history. As with memory, you can select the history page and recall the calculation result.

+/-
Reverse the sign of the calculation result. Since it does not affect calculation formula under calculation, please change the sign by character deletion. Press and hold to switch screen display mode (bright / dark) alternately. Please note that the memory contents will be erased at this time.

%
It corresponds to the percent calculation as follows.
1,000 - 5% = 950 (discount calculated)
1,000 + 8% = 1,080 (tax-inclusive price calculation)
1,000 × 5% = 50
1,000 ÷ 5% = 20,000
