How to use the buttons on the calculator 1. The AC key on the calculator is called the clear key, which is the abbreviation of All Clean in English, which means to clear all. During the number input, pressing this key for the first time will clear all the values outside the memory content. This is what people often call “clearing”. 2. MU”: mark-upandmark-down, calculate interest rate and tax rate The usage of “MU” is as follows: Markup calculation: 100+100×5%=105 (100×5 MU=105) Change rate: 100=80+80×25% (100－80 MU=25) List price calculation (cost is 120, 25% of profit list price): Just sell the price to get: 120÷25 MU=160, the profit only needs to press one more MU: 40 (profit) 3. MC: Memory Clean means “return to zero” the currently memorized number 4. MR: Memory Recall means to present the currently calculated number. These two function keys are used in conjunction with M+ and M-. 5. M+: Put the currently displayed value in the memory, interrupt the digital input, and let the calculator remember the addition (memory +) 6. M-: Subtract the current display value from the memory content, interrupt digital input, and let the calculator remember the subtraction when doing subtraction calculations. Secondly, M+, M-, MR, MC are a set of combination keys that will store numbers for operations. M+ is to store the currently displayed value for addition calculation. For example, if you want to calculate the result of 12*2+5*3, then you can enter 12*2, M+, 5*3, M+, so that the two products can be combined. Add and press MR again to read the result of the addition. 7. The function of “GT” is to accumulate the value after the equal sign. For example, if you first enter 45*2= to get 90, then enter 12*2= to get 24, and then press the GT key, it will automatically Add up 90 and 24 to get 114. As long as you don’t press the AC key, you can keep adding up, and the screen will also display the word “GT”. 8. The CE key is an error correction key (abbreviation for CLEAR ERROR)
