# Google calculator - it's no TI-89, but it's pretty cool

Summary: As I was wrapping up some coursework last night, I cut and pasted a modulus expression into my Google search bar, hoping for some references on how to solve a particular problem. Google instead offered a solution to the problem and pointed me to their calculator function.

As I was wrapping up some coursework last night, I cut and pasted a modulus expression into my Google search bar, hoping for some references on how to solve a particular problem. Google instead offered a solution to the problem and pointed me to their calculator function. In addition to the proposed solution, I was offered a link to search for documents containing my search string as well.

This is actually an incredibly handy feature, since any search string entered into Google that looks like a math problem gets solved. This includes units conversions (actually a separate feature), trigonometric functions, logarithms, roots and powers, factorials, and combinatorics. Wow. While it hardly rivals full-featured graphing calculators, it's a useful tool that beats the built-in Windows calculator. Who doesn't have a web browser open all the time? Learn the keyboard shortcuts and this could be yet another reason why I'm happy to sell my soul to Google.

## Talkback

• ### Google Search Bar in Firefox

This even works using Google's search bar in Firefox 2.x
• ### Better yet in firefox

If you don't even click enter, the suggestion box that usually shows auto-completed results shows the solution, without even going to google's page!
• ### I agree

it pretty much solve my equation, so it's worth it, if you say TI-89, then you are right, it's not related, specially on graphical equations that involve graphs as answers.
• ### My favorite example

They list as an example this calculation: 1.21 GW / 88 mph

I love Google's sense of humor.

The Google calculator is a great option for students with physical challenges. Because it is on the Internet and can use keyboard shortcuts it becomes readily accessible.
