Relationships between numbers can be helpful in making predictions or determining future behavior of phenomena. Often the relationships are impacted by multiple factors or variables. You have solved systems of equations in your algebra studies using methods such as substitution and elimination to find important points of intersection between two equations. There are numerous applications of systems of equations: for example, comparing the nutritional information of recipes, determining how much different cell phone providers charge for their services, or deciding which vacation package is the best deal. As systems become more complex, matrices, or arrays of numbers, can be used to solve or manipulate multiple layers of data.
::数字之间的关系可以有助于预测或确定未来现象的行为。 关系往往受到多种因素或变量的影响。 您在代数研究中用替代和清除等方法解决了方程式系统, 以找到两个方程式之间重要的交叉点。 方程式系统有许多应用: 例如, 比较食谱的营养信息, 确定不同手机提供者的服务收费多少, 或者决定哪种休假套餐是最好的交易。 随着系统变得更加复杂, 矩阵或数字阵列可以用来解析或操纵多层数据 。
