Math Scientific Calculator is a free Android application developed by Michael Sang Do. It is a fast and simple calculator that can perform basic mathematical operations such as addition, subtraction, multiplication, and division. Additionally, it can also calculate trigonometric functions like sine, cosine, and tangent. It can also calculate roots and powers.

The user interface is straightforward and easy to navigate. The buttons are large and responsive, making it easy to input numbers and operators. The app is lightweight and does not take up much space on the device.

Overall, Math Scientific Calculator is a useful tool for those who need to perform quick calculations on-the-go. However, it lacks advanced features that some users may require for more complex calculations. It would be great if the developer could add more functions in the future, as promised, once the app reaches 100 downloads.
