Instruction Manual: Power supply: This calculator is powered by solar cell and one AG 10 button cell battery. This unit can operate under any artificial light. When the display dims, the battery needs to be replaced. Auto power off: This unit automatically switches off it not operated for approximately 8 minutes. Power can be restored by pressing the On/C-CE key. Addition and subtraction: 123 + 456 - 789 = minus 210: Press (On/C-CE) 123 (+) 456 (-) 789 (=). Division: -3 / 4 = minus 0.75: Press (On/C-CE) 3 (+/-) (/) 4 (=). Calculations with a constant: 12 x 2 = 24: Press (On/C-CE) 12 (x) 2 (=). 12 x 5 = 60: Press 5 (=). 12 / 12 = 0.25: Press (On/C-CE) 3 (/) 12 (=). 6 / 12 = 0.5: Press 6 (=). Memory calculation: (12 x 4) - 20 / 2 = 38: Press (On/C-CE) (MRC) (On/C-CE) 12 (x) 4 (M+) 20 (/) 2 (M-) (MRC). Multiplication: 45.6 x 7.89 = 359.784: Press (On/C-CE) 45 (.) 6 (x) 7 (.) 89 (=). Power calculation 2 to the power of 3 = 8. Press (On/C-CE) 2 (x) (=) (=). Percentage 150 x 20% = 30: Press (On/C-CE) 150 (x) 20 (%). 150 x (1 + 20%) = 180: Press (On/C-CE) 150 (+) 20 (%). 150 x (1 - 20%) = 120: Press (On/C-CE) 150 (-) 20 (%). Square root: Square root of 9 = 3: Press (On/C-CE) 9 (Square root button).
