RedCrab - The Calculator
Solve complex equations in seconds with this powerful calculator

RedCrab is a versatile scientific calculator with a host of powerful features.

The program allows you to work in a very natural way, for instance, entering formulae in a full screen editor. You're able to enter complex equations with fractions, exponents, integrals, square roots and more. And you're not restricted to just one: the program will accept several equations on the same page, with the result from one being carried to the next.

If this sounds complicated, then it can be, depending on what you're doing. But RedCrab is generally very smart about how it interprets your expressions, and in most cases it'll figure out what you need first time. And when it does, you can then save and load complex formulae for easy reuse later.

You don't have to get involved in complex math every time you use the program, though. RedCrab also works well for more basic calculations. And it's portable, too, so if you need to do math on the move then there are few better options - just install it on a USB flash drive, then call up the program when you need it, on any convenient PC.

Version  6.18 (see changelog for more):

- Cumulative update with new features, bug fixes and improvements
- Display of tables improved
- Function Rndand URnd improved
- New function Rndf and more improvements in details.

Verdict:

If even Windows 7's revamped calculator isn't powerful enough for your needs, give RedCrab a try - it's smart, and packed with useful features.

WhatsApp Messenger 2.17.42

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

What's New in Version 2.17.42

• Pin chats to the top of your chat list, so you can quickly find them. Just swipe right on a chat and tap the pin icon.
• You can now send documents of any type. To send a document, open a chat, tap attach — document. 
• When you receive multiple photos, you can now tap and hold on the group of photos to quickly forward or delete all of them.
