Abstract
A method for solving and answering an arithmetic or algebraic problem using natural language processing (NLP) is provided. The method may include receiving an input statement associated with the arithmetic or algebraic problem. The method may also include determining whether each sentence within a plurality of sentences associated with the input statement is a well-formed sentence from a mathematical perspective. The method may further include converting each statement into a well-formed sentence based on the determining whether each sentence within a plurality of sentences associated with the input statement is a well-formed sentence from a mathematical perspective. Additionally, the method may include converting each well-formed sentence into a mathematical equation to form a set of equations. Also, the method may include solving the set of equations to compute a mathematical result. The method may include narrating the mathematical result in natural language.
