2.代数式运算各种各样的数学运算中,代数式运算是很基本的,因而也是很重要的运算.因为数学中的其它运算,诸如三角的、平面几何的、立体几何的、解析几何的、微积分的、……等等运算都要用到它,在数学之外的学科,如物理的、化学的运算也离不开它. Algebraic operations Algebraic operations are very basic in algebraic operations and are therefore very important operations because of other operations in mathematics such as trigonometry, planar geometry, solid geometry, analytic geometry, Calculus,..., and so on are all used in it, and in mathematics other disciplines, such as physical and chemical calculations, are also inseparable from it.
