In the realm of geometry, a line segment is a fundamental concept that represents a portion of a straight line. Unlike a line, which extends infinitely in both directions, a line segment has a defined beginning and end, marked by two distinct points called endpoints. These endpoints serve as the boundaries of the line segment, encompassing all the points on the line that lie between them.

Le subjonctif est un mode grammatical qui exprime l’incertitude, le désir, l’émotion ou l’hypothèse. Il est souvent utilisé dans les phrases subordonnées, introduites par des conjonctions comme “que”, “pour que”, “afin que”, “sans que”, etc. Le subjonctif est un mode “irréel”, c’est-à-dire qu’il exprime une action ou une situation qui n’est pas nécessairement réelle.

re-algebra is a math course that helps students prepare for algebra, which is a more advanced math course. • Pre-algebra covers important topics like working with different types of numbers, ratios, percentages, and basic equations. • Doing well in pre-algebra can help students succeed in college and other areas of life.

This text is intended to be part of a College Algebra course which exposes students to this philosophy. Such a course will almost certainly be a compromise, particularly if it must be taught in a lecture/recitation format to large numbers of students.

Algebra uses letters called variables to represent unknown numbers and combines them with numbers and operations to form expressions. • Equations are statements showing two expressions are equal, and solving them involves isolating the variable on one side using steps like combining like terms, distributing, and adding or subtracting inverses. • Variables in equations can be dependent, meaning their value depends on another variable, or independent, meaning their value is not affected by other variables.
