Calculators

Math is hard. Sometimes, even putting down expressions in numerical form is difficult, let alone solving or simplifying them. That’s where calculator applications such as SpeedCrunch and fxSolver come into play. Though the built-in calculator applications on your phone or computer may often suffice, sometimes the extra robust ability of the other software on this page can be a real lifesaver.
