In algebra, letters are used when numbers are not known. Algebraic terms, such as \(2s\) or \(8y\), leave the multiplication signs out. So rather than \(2 \times s\), write \(2s\), and rather than \(8 ...

In algebra, letters are used to stand for values that can change (variables) or for values that are not known (unknowns). A term is a number or letter on its own, or numbers and letters multiplied ...

Parsing algebraic expressions is always a pain. If you need to compute, say, 2+4*2, the answer should be the same as (2 + (4 *2)), not ((2 + 4) * 2) — in other words, the right answer is 10, not 12.

Use tiles to represent variables and constants, learn how to represent and solve algebra problem. Solve equations, substitute in variable expressions, and expand and factor. Flip tiles, remove zero ...

Abstract: For the interactive computer algebra system (CAS), to solve the matching problem of different mathematical expressions between students and CAS, this paper proposes a mathematical expression ...

BaceQG is a boolean algebra question maker for classes including but not limited to machine structure, digital design, and other classes that take boolean algebra as an important concept. Before ...

Abstract: The word “algebra” refers not only to a section of mathematics, but also to one of the specific objects studied in this section. “Algebra” in the narrow sense of the word is not considered ...
