Now, office calculators have many functions for office supplies, but many people do not know how to use them. They are unclear about the functions of each button. Below is a complete list of calculator functions to provide some reference for those who need it!
C: Clear button. During number input, pressing this button for the first time will clear all values except for the memory content. If it is a solar calculator, pressing this button while the calculator is closed will turn on the power and display "0" on the screen.
AC or CA key: Clear all button, also known as the total clear button. Its function is to clear all numbers displayed on the screen.
→: Right shift key. Its function is to shift the screen value to the right and delete the last digit on the right.
CE: Partial clear key, also known as the correction key. Its function is to clear the currently entered number, not the previously entered values. If the number just entered is incorrect, pressing this key will clear it. When the correct number is entered, the original operation continues. For example, in the calculation 5+13, if you find that 13 was entered incorrectly, you can press the CE key to clear the 13, but keep the number 5. It is worth noting that after entering a number, pressing the +, -, /, * keys, and then pressing CE will not clear the number.
MC: Accumulative clear key, also known as the memory clear key. Its function is to clear the stored data and memory content, only clearing the numbers in the memory. It does not clear the numbers displayed on the screen.
M+: Memory addition key, also known as the accumulation key.
It calculates the result and adds it to the stored number; used for memory functions, it can be continuously added, putting the current displayed value in the memory (i.e., adding the displayed number to any numbers already in memory and storing the result in the memory, but not displaying the sum of these numbers).
M-: Memory subtraction key, also known as the accumulation subtraction key.
It calculates the result and subtracts the currently displayed value from the numbers stored in memory (i.e., subtracting the displayed number from any numbers already in memory and storing the result in the memory, but not displaying the difference between these numbers).
When calculating "50-(23+4)", enter "50" first, press "M+" (store "50"), then enter "23+4", press "M-" (the result is "27"), then press "MR" (subtract the stored "50" from the current result of "27") to get the result of "23".
