Bing Vs. Google Vs. WolframAlpha Comparison

Over the weeked end I needed to find answer to one of the math problem for kids school homework.

(3/2 + x) / 2 = 3

I decided to check out Bing's Decision engine. Surprise, it gave correct answer. I guess microsoft integrated Microsoft Math software algorithm to Bing.com engine.

I also tried in Google, but came up nothing. I tried to find any google math engine, but nothing available.

I wish Microsoft also provides the series of steps needed to resolve the math problem will attract more students to use Bing.
