Chapter 52: Icons Mathematics
1. What is the “Icons Mathematics” Page?
This page collects only the icons that represent mathematical symbols, operations, geometry, functions, equations, calculators, percentages, infinity, square root, division, multiplication, addition, subtraction, equals, not equals, greater/less than, integrals, sums, pi, and other math-related concepts.
These icons are extremely useful for:
- Mathematics education websites / blogs / tutorials
- Online calculators / equation editors
- STEM (Science, Technology, Engineering, Math) course platforms
- Scientific papers / LaTeX-style documentation
- “Math Solver” or “Step-by-Step Solution” apps
- School / college assignment portals
- Physics / engineering dashboards (formulas, graphs)
- Quiz / test / exam interfaces
- “Show Equation” or “Calculate” buttons
In Font Awesome 5 free, the Mathematics category is small but very focused (around 15–25 icons, mostly solid fas style). Newer versions (FA6/7) added many more (square-root-variable, function, integral, sigma, pi variants, divide, multiply, equals, not-equal, greater-than-equal, less-than-equal), but FA5 free already has the most essential math symbols that are still widely used in educational websites, math blogs, and scientific tools in 2026.
2. Main Free Mathematics Icons in Font Awesome 5 (From the W3Schools Page)
Here are the most important and frequently used free ones you’ll see in the table (solid fas unless noted):
- Plus ➕ (addition) <i class=”fas fa-plus”></i>
- Minus ➖ (subtraction) <i class=”fas fa-minus”></i>
- Times × (multiplication) <i class=”fas fa-times”></i>
- Divide ÷ (division) <i class=”fas fa-divide”></i>
- Equals = (equals sign) <i class=”fas fa-equals”></i>
- Not Equal ≠ <i class=”fas fa-not-equal”></i>
- Greater Than > <i class=”fas fa-greater-than”></i>
- Less Than < <i class=”fas fa-less-than”></i>
- Greater Than Equal ≥ <i class=”fas fa-greater-than-equal”></i>

- Percentage % (percent sign) <i class=”fas fa-percentage”></i>
- Infinity ∞ <i class=”fas fa-infinity”></i>
- Square Root √ <i class=”fas fa-square-root”></i> (or fa-square-root-alt)
- Integral ∫ <i class=”fas fa-integral”></i>
- Sigma Σ (summation) <i class=”fas fa-sigma”></i>
- Pi π <i class=”fas fa-pi”></i>
- Calculator 🖩 <i class=”fas fa-calculator”></i>

- Superscript x² (exponent / power) <i class=”fas fa-superscript”></i>
- Subscript x₂ (subscript) <i class=”fas fa-subscript”></i>
These are the core free Mathematics icons in FA5 — very clean and instantly understandable for any math-related content.

Got it now? Want me to:
- Build a full “Mathematics Tutorial” or “Online Calculator” demo page with these icons?
- Show how they look when used inside real equations (with superscripts/subscripts)?
- Compare FA5 vs FA6/7 mathematics icons (way more symbols & variants in newer versions)?
- Or move to the next category like “Icons Medical” or “Icons Household” (wait — we already did Household)?
Just tell your teacher — we’re solving equations today! ➕✖️÷=∞√🚀
