Examples of Algebraic Expressions: x + 3, 4xy + 7, 2y – 5, etc Algebraic Expressions are formed using variables (letters) and constants. In the expression 4xy + 7, the x and y are the variables ...

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

Parsing algebraic expressions is always a pain. If you need to compute, ... If that was too fast, read the post which has a nice flowchart and an example step-by-step parse of 1+2-3*4+5/6^7-8*9.
