My Calc

This simple calculator is designed to be convenient in everyday life and fulfill the basic needs of the user in elementary quantitative calculations. It performs the evaluation of expressions written in a string, while maintaining the precedence of the mathematical sign and the precedence of calculations in the subclasses. Also supports negative and fractional numbers. Its main feature is the inability to make a mistake in typing a mathematical expression, it simply does not allow you to make a typo. All calculations are logged and can be viewed later, even after the application has been closed. After receiving the answer, you can continue the calculations further using the received answer. Just continue typing starting with the desired mathematical sign and the answer from the previous calculations will be substituted into the next expression.
