ALJ-ibr-uh/ˈældʒɪbrə/

Algebra is the branch of mathematics that uses letters to stand for numbers (usually uncountable): linear algebra; an algebra question. Arithmetic is number work without letters; equation is a statement that two sides are equal (already related). Show the algebra in the working, then the solution. Mix-up: algebra vs algae; Algeria; do not write algebra for a bar chart with no letters.
