This virtual keyboard gathers 138 mathematical symbols across 47 keys: Greek letters, operators, relations, set notation and arrows, ready to copy into homework, an article or a message.
The layout reaches 90 characters that an ordinary Latin keyboard does not carry: ¬ ° ± ² ³ · ¹ × ÷ α β γ δ ε ζ η θ ι κ λ μ ν ξ ο π ρ σ τ υ φ χ ψ ω ‰ ⁰ ⁴ ⁵ ⁶ ⁷ ⁸.
44 further characters come from the AltGr key (Alt on mobile): ³ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ ₀ ± ÷ ⁰ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ ⁺ ⁻ × · ¬ ∧ ∨ ⇒ ⇔ ←.

How to type in Mathematics
Click the on-screen keys or type on your physical keyboard — both write into the same text area.
Shift shows the second layer of every key: capitals and the characters printed at the top right.
AltGr (Alt on mobile) shows the third layer, the characters printed at the bottom right.
The Copy button puts the whole text on the clipboard, ready to paste into an email, a document or a form.
The Google, YouTube and ChatGPT buttons run a search with the text you typed, without retyping it.
Key reference table
Each row is one physical key: the base character, the one produced with Shift, then the one produced with AltGr.

Frequently Asked Questions
How do I type Greek letters like α, β, π?
Greek letters are located on the main layer of the keyboard. You can find common letters like alpha (α), beta (β), and pi (π) directly on the keys. For uppercase Greek letters (Γ, Δ, Π), use the Shift key.
How do I type mathematical operators like ∑, ∫, √?
Mathematical operators are mostly found on the Shift layer. Press the Shift key to access symbols like summation (∑), integral (∫), and square root (√).
How do I type superscripts and subscripts (x², x₀)?
Superscripts like ¹, ², ³ are on the main and AltGr layers. Subscripts like ₀, ₁, ₂ are available on the AltGr layer.
How do I type logic symbols like ∀, ∃, ⇒?
Logic symbols are distributed across the Shift and AltGr layers. Use Shift for quantifiers (∀, ∃) and AltGr for arrows and logical connectives (⇒, ⇔, ∧, ∨).
Can I type equations for LaTeX?
This keyboard produces Unicode characters, not LaTeX code. However, you can copy the text and use it in documents that support Unicode math symbols.
How do I type the infinity symbol (∞)?
The infinity symbol (∞) is located on the Shift layer. Hold down the Shift key to see it.
What is the difference between ×, ·, and *?
This keyboard offers multiple multiplication symbols: the asterisk (*) for programming, the cross (×) for standard arithmetic, and the middle dot (·) for algebra. They are available on different layers.
Can I use these symbols in Word or Google Docs?
Yes, absolutely. Once you've typed your formula, copy and paste it into any text editor or document. The symbols are standard Unicode format.
