I'm Calculator Plus - the perfect calculator for Android. I'm easy to use and beautifully designed to do things better than your phone or handheld calculator ever did.
I'm big, easy to read, and I love saving you time and effort. I remember everything you calculate, and let you review it anytime, making me perfect for shopping, doing homework, balancing checkbooks, or even helping with taxes. And if you need to quit and go do something else, I'll have it all waiting for you when you come back. You'll never need to type the same calculation twice again.
I'm attractive and effective and I make great use of your big, beautiful display:
- I show your calculations in clear, elegant type that's easy to read, with commas just where they should be
- You'll never lose track of where you are in a calculation - I show you exactly what's happening at all times
- I remember everything, so you can take a break, then come back later and pick up where you left off
- You can use backspace anytime to correct a simple mistake, instead of starting over
- Use memory to keep a running total you can actually see
- Swipe memory keys aside if you need more advanced math functions
- My percentage key shows exactly what it did, so you're not left confused
- My intuitive, lovable design makes it simple to do everyday calculations on your phone or tablet
Let Calculator Plus on your phone or tablet finally put that handheld calculator to rest.

A simple calculator, the display of which indicates expressions and gives easy operation for editing.
The calculator PanecalST includes features below:
*Four arithmetic operations, root, percentages, and tax calculations
*Calculations with parentheses
* Memory, M+, M-, MR, MC
*Scroll up/down lines
*Easy editing by using a cursor operation
* Cut, copy, and paste
*Expressions history and answer history
*Configurable grouping separator and decimal point
Four arithmetic operations:
1 + 2 - 3 × 4 ÷ 5 = 0.6
√( 2 × 2 ) = 2
500 + 20% = 600
500 - 20% = 400
500 × 20% = 100
100 ÷ 500% = 20
500 Tax+= 525
525 Tax-= 500
( 1 + 2 ) × ( 3 + 4 ) = 21
( 1 + 2 ) ( 3 + 4 ) ( 5 + 6 ) = 231
Grouping separator and decimal point:
123,456,789.1 + 0.02 = 123,456,789.12
123.456.789,1 + 0,02 = 123.456.789,12
(Depends on setting)
You can select the appropriate one depending on the calculation window Since there are two.
(Example of the use of 2 screens)
