Optically, reading of the text from an image is made easier through the use of OCR. However, we can able to use the feature of OCR to solve some of the mathematically written expressions also. As we know by doing some coding Computer system is also made to solve mathematical problems that we give as input to it. Handwritten Mathematical expression Solver helps to find the solution of handwritten or documented expressions on a computer system. The system automatically translates scanned images of handwritten, typewritten or printed mathematical expression into a machine-encoded expression. This automatic translation of the text of image into machine-encoded text is processed by optical character recognition (OCR).OCR is an optical or mechanical conversion of typed, handwritten or printed text into machine-encoded text. After the conversion, the machine-encoded text is again converted into expression which is going to get solved by the system and finally the result of the mathematical expression is going get generated as an output on the system screen.
