These functions use only the value in the main view window. For example, to calculate the square root of 8: Key Display Comments C/CE Tap twice to clear the display 8 8 Performing Arithmetic powerOneTM 10 Infinity Softworks square root 2. 83 The following are one-variable math examples: Operation Example Keystroke Reciprocal 5 [1/x] 1/5 Square 8 [x2] 82 Square root 8[square root] 8 these functions are available by selecting the "Math" button. Answer 0. 20 64. 00 2. 83 Parentheses Parentheses are used in standard input mode to establish order of precedence. Any operation enclosed in parentheses are calculated before the operations outside of parentheses. Access the left and right parentheses by selecting the "Math" button. If the equation ends in a series of parentheses, use the equals (=) button to compute the final amount. To view intermediate results, tap the right parenthesis for each left parenthesis until the value in the visible view window stops changing, then press equals button for the final value. Without parentheses, the problem 27 + 3 x 8 equals 240 because the calculator performs 27 + 3 = 30 x 8 = 240. To follow order of precedence rules, the problem should read 27 + (3 x 8). This Performing Arithmetic powerOneTM 11 Infinity Softworks forces the computation 3 x 8 (or 24) before adding 27. The total for the example with parentheses is 51. Memory The powerOne calculator has one memory location, plus the system clipboard. To access a memory location, use the store (M+), recall (MR), and clear (MC) functions. To access the system clipboard, use copy and paste from the edit menu. To store to a memory location, enter the number and select the M+ button. This will add the entered number to the amount already in the memory location. It will also display the "M" indicator in the view window. To recall a value, select the MR button: Function Key Clear the memory location MC Store 34. 5 24. 5 [M+] Recall the contents of the memory location [MR] To store to the system clipboard, enter the number then select copy from the edit menu. This allows numbers to be moved from one application to another. Recall information from the system clipboard by selecting paste from the edit menu. Memory Arithmetic Performing Arithmetic powerOneTM 12 Infinity Softworks The powerOne calculator lets you easily add a string of subtotals together in the memory location. To do this, enter the computation and select M+. Then enter the next computation and M+ again. For example, to calculate (3 x 5) + (8 x 2): Key Display Comments Memory Clear 0. [. . . ] Sets the display to its default values Bill 45 Tip% 15 Compute the total per person (Ttl/Person) by selecting "CPT" on the same line. Each person should contribute $12. 94. Example: For the example above, the company will pay the entire bill instead. Compute the tip amount by selecting "CPT" on the same line. Compute the total bill by selecting "CPT" on its line.
