I am making a forum for Math students for high school (GCSE, A-Level, SATS, and Grades 10, 11, 12). And I am trying to fill it with content. I will provide a website with some A-Level Math exams. Your job is to look through some of those past exams and more importantly the "Examiner's Report" for the exams. Look for points that students found difficulties in based on the examiner's report, and try and come up with questions **as if you were the student**. Attached are examples of what I've done for the A-Level Core 1 past exams. Your job is to do a similar thing for A-Level Core 2 and perhaps other like Mechanics 1, 2, Stats 1, 2... Remember, I don't have any rights to those questions. So copying anything is strictly prohibited.

Translate our existing math tutoring step by step teaching explanations to Portuguese and continue to maintain them as we add new things and or make changes to the English versions. The project will be largest in the beginning but then ongoing work can continue and there will also be an opportunity to assist with Portuguese language customer support which also requires some level of high school math skill (algebra, trigonometry, calculus) to best understand what users are trying to say. We will also need to maintain the translations as the development team changes the English explanations.

1-8th Grade Mathematics Curriculum Developer: Excercises I am looking for a group of organized personnel that can create mathematics problems and provide multiple problems recreated with different concepts that will have students develop solutions using different methodologies. We are looking for contractors that will do one of the following: Generate large amounts of problems for a specified mathematics topic. This person must effectively generate problems with answer keys given examples and the topic with a brief description. Generate an in depth description of how to solve a certain type of problem using the proper language for a target audience while covering the strategies and methods to solve the problem using examples and walk through problems. This will not be a short project. You will need to cooperate with others to get this project done. I am also looking for a person that can do this while staying organized and on task. While previous teaching experience is not...

I have created a non-linear constrained optimisation algorithm in excel to solve a finance problem. However, excel and the various plug-ins I have used are extremely inefficient. I now want help to write the algorithm in a more efficient language/program. The idea would be that I can understand and use the finished product. A brief description of the algorithm: There is a simple objective function/equation that needs to be maximised. There are 100 input variables which are weightings of stocks that make up a portfolio. The objective function is quadratic with respect to these inputs. There are a number of constraints placed on the model that must be satisfied for the maximised objective function (again, some are non-linear). There is also a very large dataset that feeds into the objective functions and constraints - these are mostly exogenous however there is a 100x100 matrix multiplication that can make the computation slow. Effective engagement would start with me explaining...
