我有一些代码没有得到任何数据什么是错误我的代码请更正它。如何解决代数方程例如10x2 + 10y-90 = 100请帮助我。在该代码中如何使用algebra.js。

Answer 1

您错过了变量定义，将脚本更改为

var Fraction = algebra.Fraction;
var Expression = algebra.Expression;
var Equation = algebra.Equation;

var expr1 = new Expression("x");
expr1 = expr1.add(2);
expr1 = expr1.multiply(4);

var expr2 = new Expression("x");
expr2 = expr2.multiply("y");
expr2 = expr2.multiply(new Fraction(1, 3));
expr2 = expr2.add(4);

var expr3 = expr1.multiply(expr2);

console.log("(" + expr1.toString() + ")(" + expr2.toString() + ") = " + expr3.toString());

这些是错过的陈述

var Fraction = algebra.Fraction;
var Expression = algebra.Expression;
var Equation = algebra.Equation;
