(30 is 50% of 60)(Input: 60 30 => 50%)3. How much 60 + 30%(Input: 60 + 30 => 78)4. How much 6 – 30%(Input: 60 – 30 => 42)5. How much 60 * 30%(Input: 60 * 30 => 1080)6. How much 60 / 30%(Input: 60 / 30 => 3.33…)Application was developed for Android 2.1 and up & tested on Samsung Captivate, HTC Inspire, HTC Hero …Thank you for choosing our soft!Application was inherited from preview free {Percentage calculator} with minor graphic improvements and additional "About…" menu.
