Since version 1.6, the function of expression calculation has been added, which allows for complex formula calculations. For example, entering the following formula "2+(18-10)/7^2+sin(1)+sqrt(sqrt(5),3)*2", pressing the calculate button or Enter will automatically yield the final result. Additionally, a "single-step solving" option has been added, which can display the calculation process of the formula step by step. Various trigonometric functions are supported, and the results of the operations can be chosen in radians or degrees, depending on the selection of the calculator's degree|radian button. To open the expression calculation function, right-click the LCD screen with your mouse, and in the pop-up menu, select the "* Expression (Formula) Calculation *" option to activate this feature.
