Action Symbol Name Meaning Example LaTeX Unicode
∎ Halmos / End of Proof (Q.E.D.) Tombstone symbol marking the completion of a mathematical theorem proof. Hence x = y. ∎ \blacksquare \text{ or } \qed U+220E
ℵ₀ Aleph-Null (Aleph-Nought) Cardinality of the countably infinite set of natural numbers |ℕ|. |ℕ| = |ℤ| = |ℚ| = ℵ₀ \aleph_0 U+2135 U+2080
ℵ₁ Aleph-One The next strictly larger cardinal number after aleph-null. Continuum hypothesis proposes 2^ℵ₀ = ℵ₁ \aleph_1 U+2135 U+2081
℘ Weierstrass p Weierstrass elliptic function or power set indicator. ℘(z; g_2, g_3) \wp U+2118
Å Angstrom Unit of length equal to 10⁻¹⁰ meters (0.1 nanometers). 1 Å = 0.1 nm = 10⁻¹⁰ m \AA \text{ or } \text{Å} U+00C5

Miscellaneous Math Symbols FAQ

What is the difference between floor (⌊x⌋) and ceiling (⌈x⌉) functions?

The floor function (⌊x⌋, \lfloor x \rfloor) rounds down to the greatest integer less than or equal to x. The ceiling function (⌈x⌉, \lceil x \rceil) rounds up to the smallest integer greater than or equal to x.

What does the Nabla or Del symbol (∇) mean?

∇ is a vector differential operator in multivariable calculus representing gradient, divergence, or curl.
