Continuous Calculation • The result currently displayed can be used as the first value in the next calculation. Ans appears on the screen, indicating that the last answer obtained is to be used in the calculation. € The previous result can also be used by the x 3, x -1, x !Y x following functions: ( x 2, 14 Variable M • You can use the variable M to compute accumulated totals which can be put into the variable M directly, or they can also be added to or subtracted from the number stored in variable M. € To clear all the numerical values in the separate variable M, press     (M+) 12 + 3 = 15 45 - 6 = 39 - 38 x 2 = 76 (Total) -22 12     (M=) 45  6  38  2     (M+) Variables • There are 9 variables. These are used for storing data, constants, calculation results, and other numerical values. € To clear a single variable, store zero into it. π  • Some scientific calculations may take longer than other types of calculations. € You can start the next calculation after the after the calculation result displays on screen. Each time you press , the data you have just entered is stored. The n = value shown on the screen indicates the number of data pairs you hove entered.
