It can be used with any type of number, in any dimension (feet, inch, millimeter, etc.) and any type of convention (non-dimensioned, linear, square or cubic). Calculating Percentages Find 18% of 500 feet: KEYSTROKES DISPLAY 0. 90 FEET 0 INCH Take 20% from 286 feet 6 inches: KEYSTROKES DISPLAY 0.
memory operation Whenever the key is pressed, the displayed value will be added to the memory. Other memory functions: FUNCTION KEYSTROKES Add to memory Subtract from memory Recall total in memory Display/clear memory Clear memory ; Memory is semi-permanent, clearing only when you: 1) turn off the calculator; 2) press ; ; 3) press ;; ; 4) press (Clear All).
Using Memory Storage Keys (M1 - M9) In addition to the standard cumulative memory (as previously described), your calculator has nine independent storage registers – M1 through M9 – that can be used to permanently store single, noncumulative values. The following example shows the use of M1 ( ). To use M2 - M9, replace the presses of the key with presses of the corresponding number key ( - ). You can replace a value in one of these memory registers by storing a new value in place of the stored value.
PAPERLESS TAPE The Paperless Tape allows you to display and review the last 30 entries of a calculation. accesses the tape mode and or scrolls forward or backward through the entries.

Calculate Costs The Cost function provides the total cost of material, based on a stored unit cost and an entered quantity of material. This is convenient for quickly calculating costs on a job that requires many of the same kind of items. Example You are doing an installation that includes 120 feet of pipe that comes in 10' lengths at $3.21 per 10' pipe.
