Google Implements a Calculator in Searches

Google's implemented a 34-button calculator as a part of its search engine functions. Now, if you're sans calculator or just feeling lazy, Googling simple arithmetic problems won't just yield you the answer, but the answer punched into a fully-functioning calculator.
While the calculator isn't fancy enough to replace Wolfram Alpha when doing higher-level mathematics, it's definitely a nifty tool to use. The calculator's also been implemented on Google's mobile search engine, where the calculator is as smooth and easy to use as an installed calculator app on a smartphone.
The calculator seems to be a part of Google's Knowledge Graph initiative, which the company just launched last month to make web searches for users much more in-depth and intuitive.

Google has had a calculator for years. I know cause I used it many a time. Only difference now is that it has a keypad.
You don't get it, the keypad is exactly why it's news.
Is this patent pending?
Yes, but this might be very slightly more convenient for what is included in the calculator.
One of the things that has always driven me crazy is how the standard windows calculator will give different results than the scientific calculator. This is is because the simple calculator ignores the order of operations. If you enter the following calculation in both calculators, you get different results:
3+2*4= results in 11 for scientific calculator.
3+2*4= results in 20 for standard calculator.
Drives me crazy that such a thing should be allowed to occur!

Why? A standard calculator doesn't have real-time memory for storing an input. You can't expect a standard calculator to consider order of operations because it calculates the operation immediately, without the knowledge of what comes next. Is it really too much to ask that the users applies the knowledge of order of operations?
To save an additional keystroke you could do Windows Key "calc" as it is the first search result
Also, "Run" has been integrated into the search box, so you can add command line arguments/switches
