Math Symbols in Excel
Formulas, UNICHAR Functions, and Custom Number Formatting in Spreadsheets
Published as part of our comprehensive math symbols knowledge repository. Integrate math symbols into Excel formulas, chart titles, custom number formats, and dynamic text cells using UNICHAR() codes and Alt shortcuts.
1. Using the UNICHAR() Formula
Excel provides the `UNICHAR(number)` formula to dynamically output mathematical characters based on their decimal Unicode value:
| Symbol | Formula in Excel | Application |
|---|---|---|
| ≠ | =UNICHAR(8800) | Formula conditions and variance alerts |
| ± | =UNICHAR(177) | Tolerance bands (e.g. ="100 " & UNICHAR(177) & " 5") |
| ≥ | =UNICHAR(8805) | KPI threshold indicators |
| ≤ | =UNICHAR(8804) | Budget cap labels |
| ∑ | =UNICHAR(8721) | Summary headers |
| Δ | =UNICHAR(916) | Change / Difference column headers |

Math Symbols in Excel Frequently Asked Questions
How do I insert math symbols into Excel cell formulas?
Use the =UNICHAR(number) formula with decimal Unicode values (e.g. =UNICHAR(8800) for ≠ or =UNICHAR(177) for ±), or concatenate symbols into text strings like ="Value: " & UNICHAR(177) & " 5".
Can I use math symbols in Excel chart titles and axis labels?
Yes, copy the Unicode symbol directly from our clipboard tool and paste it into chart titles, series names, or custom number formatting strings in Excel.
