Quadratic Formula PQ 对比 Linear Equations Tutor 的使用情况和统计数据

This app uses the pq formula for finding the zeros of a function quickly and easily. For this, only the values for pq must be entered. All calculations are stored in the history. The final solution can be shared. [ Content ] - the values for p and q must be entered - calculation of the zeros of a function with the pq formula - history function that saves input - complete solution - the entering of fractions is supported - option to remove ads [ Usage ] - there are 2 fields for entering the values using a modified keyboard - if you have not entered enough values, the text fields are highlighted in yellow - if you have entered invalid values, the corresponding text field is highlighted in red - you can switch between the solution, input view and history by swiping and / or touching the buttons - the entries in the history can be deleted or sorted manually - if you select an entry in the history, it will be loaded automatically for the calculation - the entire history can be deleted by pressing a key

Linear Equations Tutor

Learn to solve linear equations. The app generates equations based on random numbers, therefore always different! For every exercise the complete solution to get to the result is also provided. In mathematics linear equations are the first step to more complex equations. For students it is very important to learn how to solve linear equations in order to continue successfully the study. The complete solution of the equation can be shared as a picture or as LaTeX code (interesting option for teachers who want to create professional texts). There are 4 levels of difficulty: -Level 1: very simple equations are proposed here, they can be solved with a few easy steps -Level 2: the equations become a little more complicated and require more steps to be resolved. -Level 3: in this level are proposed equations with fractions. -Level 4 (in-app purchase): the types of more complex linear equations, with double fractions.
