Usage:

1. When typing a number, press the corresponding number key. If you press the (CE) key incorrectly, the value can be eliminated once, and then enter the correct number again.
2. After entering the number directly, press the multiplication sign to turn it into a multiplier, and press the (=) key directly without input of the multiplicand, which is the value of the number to the second power.
3, the square root of default is to open a quadratic root (┌) key, can open multiple root only scientific calculator.
4. Press (+/-) to change the positive or negative value of the number.
5. When the number is entered and the operator symbol is determined, pressing the (%) key will turn the result into a percentage operation. For example: 17+28 (%) =17%+28%, 1-90 (%) =100%-90%. The above % usage has not been verified because I have not used WIN7. I hope the person who USES WIN7 can verify whether it is as mentioned above. In Windows XP, 17+28 (%) =17+17*28%, and the percentage cannot be directly involved in the operation, but only a few percent of the previous operation. The same is true for most mobile phones, such as NOKIA.
6. Some standard models have digital storage functions, including four keys: MRC, m-m -, M+ and MU. After entering the number, press M+ to read the number into memory. After that, no matter how many steps are performed, the previously stored number can be read by pressing MRC only once. Press M- to delete the number from memory, or press MRC twice. MU is the interest rate calculation, using an unknown method.
For example, if you square 10, you can press 10 and then you can press x and then press = and you get 100
