Math assignments can be dull and most children would rather play video games or watch movies. With Math: Decimals Multiplication, they can finally do at least one of those while practicing their math homework, and the results are pretty good.

There is some setup involved, so you might need to lend a helping hand as the game starts up. First, they enter a name, before choosing an avatar and outfit for that avatar. From there, they are asked to complete a short warm-up exam, and then the games unlock. The games are unique and thematic, though the actual math is … Read more

The concrete nature of math and its focus on dry numbers and decimals make it hard to really engage students who are not already interested in the subject. So games like Math: Decimals Division are a welcome tool for any parent that wants to really inspire their child to try harder. While you'll need to pay up for more than the basics, and we found a few minor bugs in the app, we can agree that this is a good game for adding some fun to study sessions.

Before you get started, you'll need to create a profile, … Read more

Math. The very word can conjure painful memories: long division, square roots, the quadratic equation.

Not only do many of us not like math; we're also not very good at it. In an international test of 15-year-olds, the U.S. placed 24th out of 64 countries.

"We don't currently, in this country, have a cultural expectation that yeah, you're going to learn math just like you're going to learn reading," said Glen Whitney. "It's OK to not be good at math."

Glen Whitney is good at math. He's got a Ph.D. in it, and is trying to change the way we think about one of our least favorite subjects. … Read more

I'll be honest. Vague phrases like "inner balance," "emotional resilience," and "coherence zone," all of which HeartMath uses to describe its new heart rate monitor and corresponding app, aggravate me a bit. After test-driving the product this week, however, I can overlook the language.

Think of the system as a mobile meditation guide. Available as of yesterday on iTunes, HeartMath's free Inner Balance app works exclusively with its Inner Balance earlobe sensor for iOS ($99), which is available at the company's online store or through many major retailers. It uses emWave technology to show the user's heart rhythm pattern (HRV) and trains the user to change that pattern to a healthier, "coherent" state.

The system is easy to set up and, more importantly, use regularly. After installing the app, simply clip the sensor to your earlobe, plug it into your iPhone or iPad using a standard 30-pin connector (you'll need a Lightning-to-30-pin adapter for iPhone 5), and tap the screen to start.… Read more

The Great Internet Mersenne Prime Search (GIMPS) project has scored its 14th consecutive victory, discovering the largest prime number so far.

The number, 2 to the power of 57,885,161 minus 1, is a digit that's 17,425,170 digits long. That's big enough that if you want to see the full text, you'll have to brace yourself for a 22.5MB download.

GIMPS, a cooperative project splitting the search across thousands of independent computers, announced the find yesterday after it had been confirmed by other checks. At present, there are 98,980 people and 574 … Read more

Apple took lots of flack for the design of the iPhone 5. The company's decision to go taller instead of wider even spawned a meme or two. Would the company -- quite literally -- take that design to the next level?

The latest rumor says Apple is, in fact, eyeing an even larger screen for the iPhone, one that's close to 5-inches in size, up big from the current 4-inch model.

Despite an earlier report today saying such a device wouldn't see the light of day until 2014, Russian Apple news site Apple Digger has lovingly put together … Read more

MyScript Calculator (iOS|Android) is an app for both iOS and Android that lets you perform mathematical operations with freehand writing of expressions on your touch screen. This app won the Mobile App Showdown award at CES 2013 and after some time spent using it, it's easy to see why.

The simple-looking interface mimics the look of graph paper. In the top right of the screen you have buttons for undo and redo, and a trash can for when you want to clear the screen completely. In the upper left you can open a menu where you can access … Read more

Google released the stable version of Chrome 24 today, adding support for IndexedDB for apps that work better offline, mathematics formulas formatted with MathML, and faster JavaScript.

The new version also comes with a range of security fixes, including two $1,000 bounties and one $4,000 bounty paid to people who found high-severity vulnerabilities. Because Chrome automatically downloads updates by default in part to patch holes as fast as possible, people just need to restart the browser to update it.

IndexedDB, under development for years, is geared to store data for use even if a Web site or Web … Read more

The Moebius House doesn't look or sound real. It's designed to be built on a Korean island in a forest growing on volcanic rock. It's inspired by the unending brain teaser known as a Mobius strip.

Design firm Planning Korea has tackled some creative projects in the past, including designs for a mega-bridge over the Han River and a cocoon-shaped house that looks like it could hide a giant insect inside. It's no wonder those same architects saw a Mobius strip as a good basis for a house.… Read more
