Ç –

Ç +

M- ─ subtracts a value from the

semi-permanent memory

(for example, 1 5 0 Ç –

Ç + subtracts 150 from the

memory).

Ç = MR ─ recalls memory value (for

example, if 150 has been stored

in memory, pressing Ç = will

display 150).

Ç o MC ─ clears memory value.

Entering Square or Cubic

To label a dimension as “square” or “cubic,”

enter the value, then press the desired

dimension key twice for square and three

times for cubic. For example, to enter 25

cubic yards, press 2 5 y y y.

Fractional Resolution

Your calculator is set to display fractional

values to the nearest 16th of an inch

(default setting). Press Ç/to access

the fractional resolution setting. Repeated

presses of /then revolve through the

available settings: 1/16, 1/32, 1/64, 1/2, 1/4,

and 1/8. Press oto exit.

Project Keys

pPaint ─ calculates volume of paint,

based on an entered or calculated

area. Finds quantity in gallons,

quarts, or pints with repeated

presses.

wWallpaper ─ calculates number of

rolls of wallpaper, based on an

entered or calculated area.

tTile ─ finds the number of tiles,

based on an entered or calculated

area. Repeated presses scroll

between numbers of tiles for

various standard tile sizes (18″,

16″, 13″, 12″, 10″, 8″, 6″, 4″, 2″, 1″,

and 24″).

Tile sizes are shown in inches, not

square inches. In other words, a 6″

tile is really 6″ x 6″, or a 36 square-

inch tile, but it is labeled as a 6″

size.

cCarpet ─ calculates carpet length

required, based on entered or

calculated area. Repeated presses

of cscroll between values for

12′, 13′, and 15′ rolls.

CConcrete ─ calculates the number

of bags of concrete required,

based on an entered or calculated

volume (for example, cubic feet or

cubic yards).

Ç • Cost ─ allows you to calculate

total material cost.
