To perform mathematical calculations in the RichTextEditor by using the CustomTool.
Since there is no in-built plugin for performing mathematical calculations, you have to use the CustomTool option and customize the tool for the desired math calculations. Syncfusion has prepared a sample by using this custom tool that generates a Dialog box to perform simple mathematical operations and to insert the result to the RTE content. CustomTool dialog box has the NumericTextboxes to enter the data for calculation. Based on the selected operation, the resultant value is added to the RTE content.
