## What is PencilCalc?

PencilCalc 
PencilCalc displays calculation results in the vertical arithmetic format taught in Japanese elementary schools.
Even when used like a regular calculator, the answers appear neatly in the traditional pencil-and-paper style, helping children intuitively understand how addition and subtraction work.

It’s perfect for classrooms, home study, or even as brain training for seniors.
You can also enjoy ad-free use for 48 hours by watching a short ad — making it safe and comfortable for anyone to use.

Main Features
	•	Displays addition and subtraction in vertical (column) format
	•	Supports numbers up to 999,999
	•	non-personalized ads only
