In algebra, letters are used to stand for values that can change (variables) or for values that aren’t known (unknowns). A term is a combination of letters and/or numbers, often multiplied together, ...

Collecting like terms means to simplify terms in expressions in which the variables are the same. In the expression \(5a + 2b + 3a - 6b\), the terms \(5a\) and \(+ 3a\) are like terms, as are \(2b\) ...

The study of algebraic entropy and topological dynamics occupies a central role in contemporary mathematics by uniting concepts from abstract algebra with the analysis of dynamical systems. Algebraic ...
