Mathematical notation

The specific restrictions on the Latex commands are as follows:

• Latex is only recognized between single dollar signs. To display mathematics, leave an empty line before and after.
• Greek letters are available: α, β, γ, δ, ε, ζ, η, θ, κ, λ, μ, ν, ξ, π, ρ, σ, τ, φ, χ, ψ, ω, Γ, Δ, Θ, Λ, Ξ, Π, Σ, Φ, Ψ, Ω
• \alpha, \beta, \gamma, \delta, \epsilon, \zeta, \eta, \theta, \kappa, \lambda, \mu, \nu, \xi, \pi, \rho, \sigma, \tau, \phi, \chi, \psi, \omega, \Gamma, \Delta, \Theta, \Lambda, \Xi, \Pi, \Sigma, \Phi, \Psi, \Omega
• Other symbols: ∨, ∧, ¬,   ⇒  ,   ⇔  ,   ⇔  , ∀, ∃, ∪, ∩,  ∈ ,  ∉ , Ø,  ⊆ ,  ⊂ ,  ⊇ ,  ⊃ , ·, o, ×, ∂, ∫, \, →,  → , {, }, (, ),  = ,  ≠ ,  ≠ ,  ≤ ,  ≤ ,  ≥ ,  ≥ ,  ≡ ,  ≈ ,  , ℓ, ℵ
• \vee,\wedge,\neg,\implies,\Longleftrightarrow,\iff,\forall,\exists,\cup,\cap,\in,\notin,\varnothing,\subseteq,\subset,\supseteq,\supset, \cdot,\circ,\times,\partial,\int,\backslash,\rightarrow,\to,\{,\},\langle,\rangle,=,\ne,\neq,\le,\leq,\ge,\geq,\equiv,\approx,\ ,\ell,\aleph
• \mathbf,\mathbb,\mathcal (the fonts look different, but this will be addressed).
• \mbox, \mathrm to include text in mathematical expressions (no dollar signs allowed in argument).
• Single level superscripts and subscripts: x², a_i
• Latex commands that are not mentioned above are displayed as words.
