Simplifying expressions - Algebraic expressions - AQA.
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.
This expression contains three types of terms: those that contain 's, those that contain 's and those that are numbers alone. To simplify this expression, collect the like terms. This gives.

In order to write algebraic expressions successfully, you must have some familiarity with fundamental algebraic operations and key terms. For instance, you must know the significance of a variable, which is a letter that acts as a placeholder for an unknown number. You’ll also need to know that the word “constant”.
LaTeX is a programming language that can be used for writing and typesetting documents. It is especially useful to write mathematical notation such as equations and formulae. HOW TO USE LATEX TO WRITE MATHEMATICAL NOTATION There are thr.
Mathematical modes L a T e X allows two writing modes for mathematical expressions: the inline mode and the display mode. The first one is used to write formulas that are part of a text. The second one is used to write expressions that are not part of a text or paragraph, and are therefore put on separate lines.
