M is displayed when there is a value in memory. Press to clear the display or cancel the current calculation without clearing the memory. Press to store the displayed value in memory. Press m to add the displayed value to the memory. Press r to retrieve the contents of memoryto determine its value or include it in your calculation. Press I to display the contents of memory and replace it with the value that was displayed before the keys were pressed. Press to clear the display and the memory (solar model). Press fe to clear the display and the memory (battery model). Fraction arithmetic Press to enter fractions. Press after = to display the fraction as a decimal. In the display, a fraction is reduced to its lowest terms when you press a function command key (, , +, -) or =. 4 5/6 (3+12/3) 78/9 456*(3+123)d789= 26171. 2. 86 Calculations 11 (1. 5107) [(2. 5106) 3/100] = 1. 57-2. 56*3100= 3456/78 = 811/13 345678 = 149250000. 81113.
