数学可谓是一门关于符号的学问.数学中充斥着大量抽象而漂亮的符号,它们不仅使数学概念、数学公式和数学定理的表述变得简洁有力,而且也极大地促进了数学的发展.比如,何数的3倍加上4等于100?同学们很快就会列出算式3x+4=100,然后确定出未知数x=32.试想,若是没有阿拉伯数字,没有符号x,+,=,解决这个问题会有多麻烦!不过,在数 Mathematics is a learned science about symbols.Mathematics is full of abstract and beautiful symbols, which not only make the expressions of mathematical concepts, mathematical formulas and mathematical theorems simple and powerful, but also greatly promote the development of mathematics. , What is the 3 times plus 4 is equal to 100? Students will soon list the formula 3x + 4 = 100, and then determine the unknown x = 32. Imagine if there is no Arabic numerals, no symbols x, +, =, to solve This problem will be how much trouble! However, in the number
