Below is the complete list of Windows ALT codes for Math N-ary Operator Signs, their corresponding HTML entity numeric character references, and when available, their corresponding HTML entity named character references, and Unicode code points. If you are new to ALT codes and need detailed instructions on how to use ALT codes in your Microsoft Office documents such as Word, Excel & PowerPoint or applicable Microsoft Windows programs & applications, please read How to Use ALT Codes to Enter Special Characters. If you want, instead of using ALT codes, you can also just quickly tap or click any n-ary operator sign in the list below to copy and paste it into your document. (Note: Some symbols might not display correctly due to device or platform limitations in character/text representation.)
