To convert a document, click File > Info > Convert.As discussed in the post Editing equations created using the Microsoft Equation Editor, the Microsoft Equation Editor 3.0 (MEE) was removed from Office installations because it has security problems and no maintenance. However, any old equations written using Equation 3.0 or using an add-in must be manually recreated if you wish to use Word 2013вЂ™s built-in equation editor. If you convert an older document to the current format, you can use Word 2013вЂ™s more powerful built-in tools to write an equation.

First, letвЂ™s see how the converter works in PowerPoint, Excel, and Word, then letвЂ™s check out the functions a program can call to perform conversions, and lastly, letвЂ™s interpret an MEE вЂњEquation NativeвЂќ binary data stream. Some equation objects cannot be converted, e.g., long division, since OMML doesnвЂ™t have a counterpart. The converter can convert most MEE and MathType OLE objects to OfficeMath. The feature sets of MEE, MathType and OfficeMath are compared in the post Equation-Editor OfficeMath Feature Comparison and Other Office Math Editing Facilities. This post describes the conversion facility that ships with Office 365. Provided the MT Extra font is installed, MEE OLE objects display correctly, but they cannot be edited unless the user installs MathType or converts them to Office native math zones (OfficeMath).

In the Object dialog box, click the Create New tab. On the Insert tab, in the Text group, click Object. Note: This hint applies to equations created in. MS Word for Windows 7.0 has a built-in equation editor that is much better than its earlier.Microsoft Equation Editor 2016 Equation Editor 3.0 Download Microsoft Mathematics Add-in for Microsoft Word and Microsoft OneNote makes it easy to plot graphs in 2D and 3D, solve equations or inequalities, and simplify algebraic expressions in your Word documents and OneNote notebooks.

This differs from Word, for which OLE objects are embedded in the text and therefore flow with text changes.The equation-editor converter converts OLE objects to native math (OfficeMath) text. For example, if you line up an equation object with text in a text box and change the text size, the text moves, but the equation object doesnвЂ™t move since itвЂ™s not part of the text. The objects are not embedded in the text of text boxes and hence donвЂ™t flow with text.

But thatвЂ™s a tricky recognition task and it isnвЂ™t handled by the converter. Ideally all these objects would end up properly aligned in a single text box. People often position a set of equation objects to lay out equations nicely.

OfficeMath requires a math font for characters supported by a math font, while MEE and MathType use a collection of non-math fonts that can be customized by the user. So, equation conversion in Word doesnвЂ™t have object/text alignment problems, although line and page breaks may change due to the use of different fonts. The same approach is used for converting MEE objects in Excel.In Word, equation objects are embedded in the text and the corresponding OfficeMath text replaces the objects in that text.

Since the OLE objects donвЂ™t display such a character, the converter fixes up equations by removing empty subscripts and converting left subscripts with no bases into normal (right) subscripts. For example, in OfficeMath, empty numerators, denominators, subscripts, superscripts, etc., display the place-holder character в¬љ. FixupsThere are two kinds of fixups performed by the converter: 1) those handling differences in the math models as described in Integrands, Summands, and Math Function Arguments and Subscript and Superscript Bases, and 2) those dealing with equation object errors that donвЂ™t affect the object display significantly but change the display of the converted math text. In any event, the converted math text typically has a different size from that in the original OLE object. If the converted math text is too large for its text box, PowerPoint decreases the font size to fit. For example, if you resize an equation object in PowerPoint, the Equation-Native binary data doesnвЂ™t change nor do the text sizes in the Windows metafile used to display the object.

The converter replaces the former pair by the latter pair. MEE and MathType use the deprecated codes U+2329 and U+232A for the wide-angle brackets вџЁ (U+27E8) and вџ© (U+27E9), respectively. It seems reasonable to have the user delete errors that are that complicated. The converted math text shows a column (equation array) of four в¬љвЂ™s although the original object shows nothing. In testing PowerPoint presentations, we found many such errors including an extreme case of an MEE subscript object with a subscript consisting of a вЂњpileвЂќ of four empty lines.

These functions donвЂ™t call operating-system OLE functions hence they can be used on all major platforms. The Office RichEdit dll (riched20.dll) exports three conversion functions: ConvertEquationFromStorage() converts the object given by an IStorage interface, ConvertEquationFromOleStream() converts the object given by the OLESTREAM Get() method (prototype defined in ole2.h), and ConvertEquationFromStdVector() converts the equation binary data in the вЂњEquation NativeвЂќ stream. The converter is implemented as part of RichEdit and uses the same TOM interfaces as the UnicodeMath/LaTeX/speech/braille build up/down facilities. APIsNow things get more technical.

Container records (rcdLINE, rcdTMPL, rcdPILE, rcdMATRIX) can contain other records including themselves and are terminated by the end record rcdEND. The MTEF data consists of a 28-byte equation-OLE header, a version header (5 bytes for MEE and 12 bytes for MathType) followed by the records for the equation. Equation Native StreamThe Design Science OLE object 'Equation Native' stream contains the MTEF binary data for a MathType or MEE object. The вЂњEquation NativeвЂќ binary format is illustrated in the next section. Enter with the EquationNative std::vector starting with the byte following the two 'Equation Native' stream headers.

In OfficeMath, the integrand follows the limits, hence the need for ITextStrings2::Rotate(). Note that the integrand precedes the integral limits. Be sure to convert the ASCII hex characters to binary, two per byte with no intervening spaces. Putting the binary into a std::vector and passing it to ConvertEquationFromStdVector(), you insert this equation into the text.
