Mathematical Symbols is a clear reference to the symbols used in school and university maths. Every symbol is shown as a real Unicode character with its code point its name its meaning a typeset example and how it is read aloud.

What the app covers
• Getting Started: how to read maths notation a Symbol Finder with more than 300 entries and look-alike symbols such as − and - ∑ and Σ ∈ and ε
• Arithmetic and Equality: operations roots percent equals and inequality signs brackets and the order of operations
• Algebra: powers roots and logarithms absolute value floor and ceiling functions sums and products divisibility and modular arithmetic
• Geometry: lines segments and rays parallel and perpendicular angles degrees and radians triangles circles congruence and similarity
• Set Theory: elements and subsets union intersection difference and complement with Venn diagrams power sets and infinite sets
• Logic: not and or implication and equivalence with a truth table quantifiers and proof symbols
• Calculus and Analysis: limits derivative notations partial derivatives gradient integrals and asymptotic notation
• Linear Algebra: vectors norms dot and cross products matrices transpose inverse determinant and eigenvalues
• Probability and Statistics: probability rules random variables and distributions mean standard deviation hypothesis tests factorials and combinations
• Number Sets and Numerals: ℕ ℤ ℚ ℝ and ℂ interval notation Roman numerals and digits in other scripts
• Greek Letters: all 24 letters with pronunciation and common meanings and their variant forms
• Constants: π e the golden ratio i √2 Euler's constant and infinity with values and explanations

Who it is for
Students at secondary school and university teachers and anyone who meets a symbol in a book or formula and wants to know what it means and how to say it.
