The Google Calculator

Google Calculator

This is an oldie but a goodie. The Google homepage has changed a little as the pics are from circa 2009.

Do you enjoy math? Are you very good at it? Okay, in other words, do you stink at math? Are you in a profession that requires you to be a genius at mathematics (however, you’re not even close to being one?) Or, do you just want to learn some different things about math?

If so, worry no more, because Google has come to your rescue yet again. No, Google hasn’t released another new software program, but they do offer a built-in calculator function right on Google’s Web site. Who knew?!

To use this, go to Google’s Web site and simply enter the expression you’d like to evaluate in the search box and hit Enter (or click the Google Search button).
Google will do everything from basic functions of mathematics to calculating inverse trigonometric functions and it will do it all for you!

For example:

We can, of course, combine the different mathematics functions together. For example, (25+49) -10. Here, the function in the brackets is calculated first (the addition happens before the subtraction).

Similarly, if you want to do advance mathematics calculations or want to help your child study for that upcoming trigonometry test, you can do that with the Google calculator. Below is a list of common functions you can use with this feature.

If you believe in pushing the calculator’s limits by making it do illogical calculations, you can force it to evaluate an expression by using the equal sign ( = ). However, this will only work if the expression is mathematically resolvable.

If the calculator doesn’t show up when you enter in an equation:
  • Make sure your equation is something that can be computed. For example, if you search for [7*9/0],you won’t see the calculator pop up because dividing by zero does not create a value.
If it still isn’t showing up, try adding = to the beginning or end of your search.

For example:
25-256898-751-36587 =

Now, Google hasn’t limited itself to just basic or advanced mathematics functions. What’s maybe more useful to most users is the ability to convert between different units. For example, kilograms to pounds, meters to miles or from one numbering system to another, etc. The point to note is that the “in” operator is used to specify what unit you want the answer in. For example, 20 kilos in pounds or 256 miles in kilometers. “In” is your easy way out.

Another point that you should consider is that when it comes to conversion, many units have both long and short names, but no matter what you use, the answer will be the same.

It even calculates cool things like how much space 10 hours of 128 Kbps sized MP3s take up.

The best way to maximize the benefit from this calculator is to experiment with it. The more familiar you are with the terms, the faster and more accurate your calculations will be. There is also a link that says “More about calculator” that you can click on to learn even more about the different things this calc can do.
