Addition and substraction

- Decimal example : 35 + 45 + 25 - 12
--->  press 35 <+> 45 <+> 25 <-> 12 <=>

- Imperial example : 3'-4" 5/16" + 1'-2 3/8" - 1'-2"
---> press 3 <Feet> 4 <Inch> 5 < /16> <+> 1 <Feet> 2 <Inch> 3 < /8> <-> 1 <Feet> 2 <Inch> <=>

- Imperial square example : 2.125 Square feet + 3.5 Square feet
---> press 2.125 <Feet> <Sq> <+> 3.5 <Feet> <Sq> <=>

- Imperial cubic example : 2.125 Cubic feet + 3.5 Cubic feet
---> press 2.125 <Feet> <Cu> <+> 3.5 <Feet> <Cu> <=>

Division and Multiplication

- Decimal example : 25.5 x 5 / 2.125
---> press 25.5 <X> 5 < / > 2.125 <=>

- Imperial example : 2'-5" 5/16" x 4'-3" / 2'-0"
---> press 2 <Feet> 5 <Inch> 5 < /16 > <X> 4 <Feet> 3 <Inch> < / > 2 <Feet> <=>

- Imperial Square and Cubic example : 3.125 Cubic feet / 1.25 Square feet
---> press 3.125 <Feet> <Cu> < / > 1.25 <Feet> <Sq> <=>

Conversion

- Converting Feet to Meter example : 10'-5" 3/16" converted in meter
---> press 10 <Feet> 5 <Inch> 3 < /16 > <Conv> <M> <=>

- Converting Meter to Feet example : 10.125 Meter converted in Feet
---> press 10.125 <M> <Conv> <Feet> <=>

Resolving Slopes

Please note that as soon as you entered two parameters, the other two ones will be calculated automaticly. Once two parameters have been entered, the result of each parameter can be displayed by pressing on each parameters buttons. The pitch of the slope is given in inch / 12 format ( the standard for roof pitch values ).

Here is a simple diagram of the terms used for defining slopes :

- If the run and the rise are known : example :
run is 4'-0" and the rise is 3'-0"
---> press 4 <Feet> <Run> and 3 <Feet> <Rise> . 
Results will be shown by pressing the <Pitch> and the <Slope> buttons.

- If the run and the pitch are known : example
: run is 4'-0" and the pitch is 9 /12
---> press 4 <Feet> <Run> and 9 <Inch> <Pitch> .
Results will be shown by pressing the <Rise> and the <Slope> buttons.

Reset the calculator

- Simply press the <Reset> button.

Correction of the last entry

- Simply press the < C > button will erase the last value entered. Note that the < C > button must be pressed before any function button ( addition, substraction, etc. )
