Math DJ

An educator who creates beautiful or elegant math, by mixing and matching ideas from different disciplines to vow their audience—they are neither generalist or specialist, who use creative ways to convey difficult math concepts, or are bewitched to come up with intuitive or elegant solutions to math problems.
