Features

- You can easily calculate percentages!

You can calculate percentages easily! Incredibly handy! Below are examples.

* Calculate the post-tax price of 5,500JPY (Japanese consumption tax is 8%): 5,500 + % = 5,940

* Work out the 25% off price of 10,000JPY: 10,000 - 25 % = 7,500

* What is 30% of 30,000JPY?: 30,000 * 40 % = 12,000

* 43% of 120,000,000 people : 120,000,000 * 43 % = 51,600,000
