For my blog post #13, I choose option #1.
1. I have never heard of WolframAlpha. I usually use search engines like Google or Ask Jeeves or Yahoo.
2. I also have never heard of Google Squared.
3. According to 2010 estimates, the percentage of China's population to United State's population is 439%. China's population is 1.35 billion people. United State's 309 million people.
4. According to 2010 estimates, the percentage of India's population to United State's population is 393%. India's 1.21 billion people.
5. Now that I researched the percentage of the different populations, the facts in Did You Know? make more sense. Wolfram Alpha breaks down the growth changes over the years.
6. I think that Wolfram Alpha is definitely a site that I will use from now on. I like how precise all of the results were. I also liked how fast the results were found. I will use this search engine in my classroom. This site has a lot to offer. You can look up information on math, history, science, and many other subjects.
