A Skill Testing (Search Engine) Calculation

To claim a contest prize, I had to answer the following skill-testing question:

1000 - 50 / 2 x 10

Okay, it’s not a problem as long as you know about operator precedence. As a developer, my brain automatically supplied brackets.

I was curious as to whether this exact skill-testing question is commonly-used in online contests, so I Googled the formula. To my amazement, Google returned the result of the calculation – complete with brackets:

1 000 - ((50 / 2) x 10) = 750 (Google)

Bing also has a calculator but it doesn’t include the brackets, and worse, clutters the page with tons of irrelevant search results:

1000-50/2*10 = 750 (Bing)

I suppose everyone else knows about these search engine calculators but to me, it was a pleasant discovery.
