Cirdm (In English: International Center for Mathematical Research and Development) is a school project involving the visual identity of a brand based on mathematics. The logo is centered on a well-known and often-used concept, the x in brackets. In this context, this universal calculation also symbolizes the mathematical variety (the x) surrounded by a sign, a place (the brackets) and thus projects the environment of this establishment. The rest of the content is sober and effective, with the two logo variants adaptable according to use.
