Untitled Note

The PM Solution is Correct if the following is true: All calculations, manipulations, definitions, theorems, and images are mathematically correct. The methods and mathematical concepts are applied correctly and in line with the terms of the task. The premise(s), conclusions, and logical reasoning used to reach them are mathematically correct. If used, PM Solver uses an appropriate solving method. 1- ALL mathematical terms and objects have to be correct and suitable for the situation. If even one term or object is incorrect or inappropriate, the solution is not correct and needs to be modified. 2- Each step in the PM Solution has to be mathematically correct. That means all conclusions, calculations, and reasoning have to be correct and in accordance with the provided task. The function is in standard form and the graph opens upwards, so those conclusions are not mistakes. Because the function from the task is wrongly copied, the solution is not in accordance with the task. 3- All the mathematical concepts must be applied correctly and in accordance with the context of provided step. For example, if inequality is going to be solved, it is not correct to write “Solve the equation”. “Solve the inequality” would be correct. The correct answer is the only one that correctly refers to an inequality that is written, instead of using incorrect concepts "equation" or "expression".
