Math Apps for Pi Day

Happy almost Pi Day! Monday is March 14, otherwise known as 3/14, otherwise known as Pi Day! It's the day we nerds celebrate the beautiful irrational number that represents the ratio of a circle's circumference to its diameter, which we commonly abbreviate to 3.14. Not everyone gets excited about Pi like a true math nerd does, but you can get excited about these cool apps that render your college algebra classes even less relevant than they used to be.

• Photomath Where the heck was this app when I was in high school? With a couple of clicks, Photomath (iOS and Android) scans and solves mathematical equations without getting out a pencil or even a calculator. Photomath also takes you through the solution step by step to teach you how it's done.
• Travelmath After TripIt, the Travelmath website is the most helpful travel tool I use. The site tells you driving distances, the nearest airport to a city and all kinds of extremely helpful calculations that make travel easier.
• Splitwise I had three roommates in college, and I still remember the phone bills with color-coded highlights and calculations that helped us divide up the bill. Splitwise (iOS and Android) does the math for you, dividing up bills, rent and more for group expenses. A new iOS restaurant tool helps you split the check.
• MyScript Calculator These apps recognize your handwriting as you write out your equations and await their simple solution.
• Wolfram|Alpha If you want to know about every single thing in the entire world and have that information at your fingertips no matter where you are, Wolfram|Alpha is what you seek. What do I mean by everything? I mean everything.
