Word users can use the insert equation option to add mathematical equation to a document. Similarly to add any Math’s Symbol, you can use Insert –> Symbol feature. This is quite useful when you are preparing Mathematics Questionnaire using Word 2010.
For example, if you want to add non equality operation, then navigate to Insert menu, click the Symbols option and pick non equality symbol from the drop down list.
If you can not find the symbols in the above list then you can click the More Symbols menu option and pick the extended list.
Another alternative way to add mathematic operation in a Word document is by using the insert Object option. Navigate to Text section under Insert menu and click the Object menu option.
Then from the Object window, select Microsoft Equation 3.0 from the Object Type list and click the OK button.
Now you can select the required symbols from the Equation window.
