ImplementA

February 13, 2024

Simplify the easy computing to reduce steps of implementing add content: abstract function f(x) one Variable Quadratic Equation compound inequaliy classification proof by contradiction/reduction to make nature inequality m>n(m-n>0) to make inequality from m>n>0 to sqrt(m)>sqrt(n) refine relative formula about the addition of rational number refine solution judge to use compound ineqaulity Clear other errors and bugs 简化简单计算以大量减少解题步骤 新增内容：
 抽象函数f(x) 一元二次方程 复合不等式 分类讨论 反证法 支持不等于不等式， 支持构造自然不等式 m>n(m-n>0) 支持从m>n>构造不等式sqrt(m)>sqrt(n) 改进有数加法相关规则的运用 改进不等式解集判定支持复合不等式 清除其它错误与bugs

update how page to show how to use app by new manner refine the ui for trigger of operation menu add new operation: |a| greater than |b|,a less than0,a+b less than 0,a greater than 0,a+b greater than 0 refine the compute number product so can compute numerator or denominator or total fraction enhance replace by opposite: support x=-(-x) display selected menu item even if unmatched to selected monomials remove bug for unmatched selection of menu item remove bug of ab no less than 0,ano less than 0,so b no less than 0 refine a div b no less than 0,a no less than 0,so b greater than 0 refine a div b no less than 0,b greater than 0,so no less than 0 refine ab.no less than 0,a.no less than 0,so b grater than 0 remove bug of no effect to set sigh to input number 更新用法頁簡單說明App的使用方法 改進觸發菜單的UI 新增數學運算：|a|大於|b|,a小於0,a+b小於0,a大於0,a+b大於0 改進計算數積以支持選擇計算分式的分子部分或分母部份或整個分式 增強替換相反數：支持 x=-(-x) 顯示選擇的菜單信息無論是否時匹配的數學操作 移除不匹配菜單項選擇的bug 移除來自 ab不小於0,a不小於0,so b不小於 0 的bug 增強 a div b不小於0,a不小於0,so b大於 0 增強a div b不小於0,b大於0,so a不小於 0 增強 ab 不小於 0,a 不小於 0,so b 不小於 0 移除輸入數時正負號設置失效的bug
