1. When typing a number, press the corresponding number key. If you press the wrong number key, you can cancel the value once, and then re-enter the correct number.2. After directly entering a number, press the multiplication sign to change it into a multiplier, and press the (=) key directly without entering the multiplVariable-Frequency Drive ier, which is the quadratic value of the number.3. By default, the root () key opens a quadratic square root. only a scientific calculator can open multiple square roots.4. Pressing the (+/-) key can change the positive and negative values of numbers.5. When a number is entered and an operation symbol is determined, pressing the (%) key changes the result into a percentage operation. For example: 17 + 28 (%) = 17% + 28%, 1 - 90 (%) = 100% - 90%. Since I have not used the above% usage of WIN7, I hope that the people who use WIN7 will verify whether the above mentioned usage is as follows. In Windows XP, 17+28(%)= 17+17*28%, percentages can not directly participate in the operation, which is a few percent of the previous operand. This is also true for most mobile phones, such as NOKIA.6. Some standard models have digital storage function, which includes four keys: MRC, M-, M+, MU. After typing the number, press M + to read the number into memory. No matter how many steps are taken, the previously stored number can be read by pressing MRC once. Pressing M - will delete the number from memory or press MRC twice. MU is an interest rate calculation, the use of which is unknown.7. Square can also be expressed: for example, 10 squares, you can Crane press 10 and then press * and then press = the result will be 100.
