From Villanova University:

Math isn’t just something you have to learn to pass tests in school. It’s something you’ll use every day of your life. Without math, we couldn’t measure things or count money. People need to know math to run a business and to keep track of their finances. Math is everywhere, and that’s why it’s so important we learn a lot of different math skills. Learning the math you need to know to get A’s in school or to go into business someday isn’t always fun, but it doesn’t have to be boring. There are a lot of free math, money, and business games online that can help you practice and master things like adding and subtracting, balancing a budget, and counting money. Play these fun games by yourself or with friends and you are sure to learn a lot. You’ll probably get a better grade on your next math test too!
