Excel COUNTIFS and COUNTIF with multiple criteria – examples of usage The tutorial explains how to use COUNTIFS and COUNTIF formulas with multiple criteria in Excel. You will find a number of examples for different data types - numbers, dates, text, wildcard characters, non-blank cells and more. Of all Excel functions, COUNTIFS and COUNTIF are probably most often mixed up because they look very much alike and both are purposed for counting cells based on the specified criteria. The difference is that the COUNTIF function is intended for counting cells based on a single condition in one range, while COUNTIFS allows using several criteria and ranges. In practice, however, you can use Excel COUNTIF with multiple criteria as well. Excel COUNTIFS function - syntax and usage As I've already mentioned, the Excel COUNTIFS function is purposed for counting cells across multiple ranges based on one or several conditions. COUNTIFS syntax The syntax of the COUNTIFS function is as follows: COUNTIFS(criteria_range1, criteria1, [criteria_range2, criteria2]…) Example 1. Tip.

The Two Online Security Steps You Should Stop Putting Off - NYTimes.com My favorite password manager is LastPass — which our friends at The Wirecutter, a New York Times company, also recommend — because it works with every browser, it works with most mobile phones, and its interface is relatively simple. Most password managers generally work the same way: You set up one master password for the manager itself, and from then on you use its browser plugin (or mobile app) to create and manage every other password you need. Every account gets a unique password, meaning that if one account is compromised (like in a mass data breach), your other accounts will remain safe. If you’re still not convinced about the paramount importance of strong password management, here’s some further reading. Two-factor authentication goes a step further by requiring a username, password and access to your mobile phone to log in to an account. And, while we’re on the subject, here are more ways to protect your identity online. Have a great week! —Tim Best of Smarter Living
Excel Formulas: Defining and Creating a Formula In this lesson, we introduce you to basic rules for creating formulas and using functions. We feel one of the best ways to learn is through practice, so we provide several examples and explain them in detail. The topics we will cover include: rows and columnsexample math function: SUM()operatorsoperator precedenceexample financial function: PMT(), loan paymentusing a “string” function (“string” is shorthand for “string of text”) inside a formula and nesting functions Formulas are a mixture of “functions,” “operators,” and “operands.” Rows and Columns To understand how to write formulas and functions, you need to know about rows and columns. Rows run horizontally and columns run vertically. Columns are labeled by letters; rows by numbers. Example: Function Sum() Now let’s demonstrate how to use a function. You use functions by typing them directly in or using the function wizard. The wizard tells you what arguments you need to provide for each function. #NAME? Calculation Operators
How to Install and Move Android Apps to the SD Card If you have an Android phone or tablet with a small amount of storage, you probably keep uninstalling apps to make room for other ones. But there is a way to expand the storage of an Android device if it has an SD card slot. By default, Android apps install to your phone’s internal storage, which can be quite small. If you have an SD card, you can set it as the default install location for some apps–thus freeing up space for more apps than you would have otherwise been able to install. You can also move almost any currently installed app to the SD card. There are a few different ways to do this, and which you use depends on your version of Android and which apps you want to move. Before we start, we should note: running an app off your SD card will almost undoubtedly be slower than running it off the internal storage, so only use this if you absolutely have to–and if you can, try to use it for apps that don’t require a lot of speed to run well. Insert the SD card in your device.
