Plus42

Plus42, although it might not give you this impression after its name, is a complex calculator software. It brings together many other types of similar machines offering a complete set of tools in one simple and tiny package. Inspired by the Free42 project, this application tries to base itself on the actual HP-42S, a programmable RPN calculator that was manufactured up until the late 90s.

Now, since we're dealing with a complex calculating machine, even if the interface is friendly if you don't have much of an idea about what each particular function does, it will all seem like a distant language to you. Regardless, the implementation of the skin and the general responsiveness are good signs for those who need this type of calculator for projects or whatever problem-solving they might be dealing with.

Some of the included perks have to deal with algebraic expressions, amortization tables, plotting functions, and integrals and roots of complex mathematical expressions. The added portability perk can only increase its usefulness. The app comes in two flavors, decimal or binary, depending on which system your find more useful.

As opposed to the real, palpable calculators out there, this virtual one has an increased screen size, allowing the user to input more than one specific calculation or expression, clearly labeled buttons, that are not susceptible to any usage damage, and an adjustable body to the height and width desired by the user. In this aspect, one can't miss how highly adaptable this program really is.

Plus42 can prove to be a useful tool for those individuals looking to work with a reliable calculator that includes vast functions from more than one specific machine. It is a virtual rendition, meaning it won't suffer from any of its physical counterpart's quirks while delivering the exact same experience in a portable and resizable package.
