This document provides examples of how to use WolframAlpha to check work by generating solutions and examples for algebra equations, inequalities, changing the subject of formulas, substitution, graphs, simultaneous equations, factorisation, polygons, circles, standard form, and unit conversions. While step-by-step solutions require a subscription, WolframAlpha allows unlimited free queries each day making it suitable for checking answers and exploring multiple examples.

1. The examples here show you how to use WolframAlpha for
checking your work and exploring other examples.
Note that step by step solutions are for subscribers only but
WolframAlpha is free to use for an unlimited number of
queries every day so it is great for checking answers or
generating lots of examples.
