大多数的数学家会由他们的工作及一般数学里得出美学的喜悦。他们形容数学是美丽的来表示这种喜悦。有时，数学家会形容数学是一种艺术的形式，或至少是一个创造性的活动。通常拿来和音乐和诗歌相比较。
伯特兰·罗素以下列文字来形容他对数学之美的感觉：
Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as poetry. (The Study of Mathematics, inMysticism and Logic, and Other Essays, ch. 4, London: Longmans, Green, 1918.)
保罗·埃尔德什形容他对数学不可言说的观点，而说：“为何数字美丽呢？这就像是在问贝多芬第九号交响曲为什么会美丽一般。若你不知道为什么，其他人也没办法告诉你为什么。我知道数字是美丽的。且若它们不是美丽的话，世上也没有事物会是美丽的了。”
它的最美之处莫过于在无形之中就让你思维变得敏捷．考虑事情时，不在那么偏激，那么单一．
作为一个公民来说了不了解它是一个后话，至少应该不否定它．尤其是学生．
