If one believes that perhaps it is incorrect, he must reenter the data on the calculator to compute the correct answer - hoping not to make mistakes the second time around. The data is displayed on a large screen and saved in a file. CalcuScribe auto-computes the results and displays them on the screen at the end of each math expression. You can move the cursor to any location to correct the mistakes, or to enter more expressions, or delete some. You may also insert text so that the reader, of your report, can understand the methodology used in solving the problem.
Schools have a mandate to integrate the writing and the math curriculums.
For example, problems and projects are presented in text form. Kids solve the problems and explain their construction, logic, results and analyses in a word processor that runs on a desktop computer or by writing reports by hand. They submit the report to the teacher for review and a grade. CalcuScribe is a simple word processing and calculating device that allows teachers to 'beam' word problems to the kids. Kids open the received file, on their machine, read the problems and, if necessary, breakup the complex problems into simpler parts by defining variables and expressions.
