1. Introduction

This software deliverable is a prototype of a word problem solver, namely a system that interactively poses a word problem, (in many languages), then constructs a solution and a reasoning context for it. The overall architecture is based on the usage of third-party, open-source software components to provide the reasoning infrastructure for the system and are not distributed in this deliverable.

This document describes:

• how to install the prototype,

• how to create word problems involving simple arithmetic;

• how to assisting a student into finding the equations related to it.

The first component is a Scala library (http://www.scala-lang.org) to be used inside the Scala Interpreter shell (in a Read-Evaluate-Print Loop), while the second component is a dialog system which runs in the command line. Both components were developed within the framework of the MOLTO project.
