For example, when "1 2" is mistakenly entered as "1 3", press "C" and then enter "2".
“M”: Let the calculator remember the addends when doing addition operations.
“M-”: When doing subtraction calculations, let the calculator remember the subtraction.
"MR": memory recall, read the storage content key, used to display the calculation results up to that time.
"MC": memory clear, delete the content saved by the memory key.
"MRC": combines "MR" and "MC", the function of pressing once is like "MR", and the function of pressing twice is like "MC".
For example, to calculate "1*2-2*3", operate in the following order: 1*2, M, 2*3, M-, MR.
"GT": grand total, total value key, the sum of the total numbers obtained after pressing the equal sign.
For example, to calculate "10*2 5*5", operate in the following order: 10*2=, 5*5=, GT.
"MU": mark-up and mark-down, calculate interest rates and tax rates.
The usage method is as follows: 1. Addition: A B MU, the calculation formula is: 100 A÷B×100; 2. Subtraction: A-B MU, often used to calculate the rate of change, the calculation formula is: (A-B)÷ B×100; 3. Multiplication: A×B MU, often used to calculate the price increase, the calculation formula is: A A×B%; 4. Division: A÷B MU, often used to calculate the bid price, the calculation formula is: A÷( 1-B%), when you press the MU key again, you can get the profit value, the formula is: A÷(1-B%)-A.
There are some simple operations when using the calculator.
Add a number together: 20 10; 20 30; 20 40
Enter "10 20=", then enter "30="; then enter "40=", that is The above three sums can be calculated separately.
Same as subtracting a number: 20-5; 10-5; 8-5
Enter "20--5=", then enter "10="; then enter "8=" , you can calculate the above three differences respectively.
Multiply the same number: 20*15, 20*16, 20*25
Enter "20**15=", then enter "16="; then enter "25=" , you can calculate the above three products respectively.
Same as dividing a number: 10/2, 20/2, 16/2
Enter "10//2=", then enter "20="; then enter "16=" , you can calculate the above three quotients respectively.
