I want to generate math courseware through code. At first, I used Java POI, but it does not support adding animations and mathematical formulas. Later, I learned that there are some methods in VBA, but I am not sure if it can add complex mathematical formulas.

I found a method to input mathematical expressions through searching, like this:

Sub WhatIsTheEquationMadeOf()
    Dim x As Long, txtBox As Shape
    word = "Solve "
    
    Set txtBox = ActiveWindow.Selection.ShapeRange(1)
    If txtBox.Type = msoTextBox Then
        With txtBox.TextFrame.TextRange
            .Font.Color = RGB(80, 122, 160)
            .ParagraphFormat.Alignment = ppAlignCenter
            .Font.Size = 22
            .Text = word & "2x^2+7x+6=0"
            .Characters(Len(word) + 1, .Characters.Count - Len(word)).Select
            With Application.CommandBars
                .ExecuteMso "InsertBuildingBlocksEquationsGallery"
                .ExecuteMso "EquationProfessional"
            End With
        End With
    End If
End Sub

but I don’t know what syntax to use to write other mathematical expressions. For example, a Fraction.
