If you're selling or giving away an old computer, you definitely want to take the time to erase its memory for privacy and security reasons. Or, your system might be running very slowly, and wiping the hard drive could speed it right up. The procedure isn't as difficult as it sounds and we'll give you step-by-step instructions.

You need to add up some numbers fast. What do you do? You could dig around in your desk drawer for a calculator. You could fish around on your computer for a calculator app. Or you could just use that Google search box you already have open in your browser. Google’s search box doubles as a quick and easy calculator. It’s pretty flexible about how you phrase your equations. For example, typing “12 x 2” or “12 times 2” will get you the same result. Google helpfully opens up a full in-browser calculator above the usual search results so you can keep going in your calculations.

Google’s built-in calculator can also handle some fancier equations. Try asking it for square roots or string together a series like “12 + 18 + 36 – 9.” If you get into more elaborate queries, remember to use parentheses so it knows what you’re asking. Searching for “12 + 5 – (2 x 2)” will get the answer you’re looking for: “13.”
