This animation introduces the concept of an oriented number line, starting with a horizontal line marked with the origin O and several points, including point A. A right-pointing arrow is added to establish the positive direction. The animation visually demonstrates how choosing this orientation allows each point to be assigned a coordinate, enabling clear comparison and localization of positions. Useful for students beginning coordinate geometry or number line concepts in French-language math courses.

Create a clean, elegant and professional mathematical animation showing the orientation of a number line. Start with a horizontal number line and clearly show the origin O and several points, including A. Then introduce an arrow pointing to the right to represent the chosen positive direction. Show visually that orienting a line means choosing a positive direction, which allows us to locate and distinguish the positions of points using their coordinates. IMPORTANT: - ALL visible text must be written in FRENCH. - NEVER use English words or English sentences. - Use standard mathematical notation for mathematical labels. - No narration and no voiceover. - Keep the animation purely visual. - Do not add unnecessary text. - Focus only on the mathematical idea of orienting a line. - Elegant, precise and visually clear mathematical animation. - 16:9 format.
