How so I change options?
Paper Calc Office's options page is to the right of the main keypad. If you touch and slide the keypad from right-to-left you will see the page. Also, in the top right corner of the options page is a button which will show a full-screen view of the paper tape.

Where are the brackets?
Paper Calc Office was designed as a simple chain calculator for short calculations. For example: What is the squareroot of 2? What was my gas mileage (330 miles / 19.2 gals). It was also designed to give an exact history of what was calculated in the past. For people who need this simplicity, brackets are actually a hindrance.

How do I use the percent (%) key?
There are two ways to use the % key:
  1. Obtain the % of a number:
    - Press '200 % 5 ='
    - Answer will be '10'
    - PaperCalc took 5% of 200.
  2. The % of a number is used in the operation on the number:
    - Press: '200 - 5 % ='
    - Answer will be '190'
    - PaperCalc subtracted 5% of 200 from 200

What are the three display formats for?
People doing general math want as many decimal places as possible (float), Someone doing monetary math wants a fixed number of decimal places (fix.n), and an engineer generally wants a power that is a multiple of 3 (eng^3). Easily access the three different formats by pressing the display format key on the main keypad.

How do I use the MEM key?

A MEM key is available if the Office+ keypad is selected (see How do I load the Office+ keypad item below). Any one of the 10 memory locations can be accessed in 3 button pushes as follows:

  1. Touch the MEM key
    • CLR, ADD, SUB, RCL, STO will show as yellow
  2. Select one of the 5 functions (for example STO).
    • The STO key will become grey and the 10 number keys will show red or green dots in the bottom left corner. Red means there is a number in the location. Green means the location is empty.
  3. Select a location (for example the 4 key)
    • The number on the LCD display will be stored in location 4

To recall the number touch: MEM, RCL, 4.

To add to the number already stored in location 4 touch: MEM, ADD, 4.

How do I make my keys larger?
Paper Calc Office has a very powerful feature for sizing your keys to your needs. Just touch the calculator's LCD display and move it up or down to re-size the keys.

I see a button for printing, but it doesn't seem to work.
Paper Calc Office supports AirPrint which allows an iOS device to print directly to a printer. The printer must be a wireless printer on the same local network as your iOS device. Also, the wireless printer must be an AirPrint printer. For example HP's printer use the term 'ePrint capable'.

How do I load the Office+ keypad or make and save my own keypad layouts?

To load the Office+ keypad touch: 'i' (info) key and select Edit Keypad Layout.

At the top of the calculator 5 buttons will appear:

  • Office and Office+ are preloaded keypads. Office+ includes a √, 1/x, pi and MEM key.
  • Save 1, 2, 3 are spaces available to store your own keypads.
Make keypads by touching any key on the keypad and moving it. Tap a key to change its size. A key will become double wide if the space to its right is empty. If keys are made half-high, they can be stacked in a single keyspace. Touch Save 1, 2, 3. The new design will be saved. Touch the same Save 1, 2, or 3 and you can recall the keypad, or rename it.
