In the business world, finances are like the weather. They can change from season to season and day to day, sometimes due to decisions made half a world away. On Monday, you can buy your competitor's business in Brazil, and on Friday, a new competitor in China may pop up to take your profits. Or, if you're a nonprofit, you may have to plan carefully to make the most of donors' dollars. Financial managers can help by acting like weathermen and weatherwomen: They prepare reports on the financial "temperature" of the economy, keeping an eye on its ups and downs, and create forecasts, helping to predict the best times for a business to cut costs or plan an expansion in the future. So if you're a fan of math, and you like the idea of tracking trends and providing advice to top business and nonprofit leaders, then the world of finance might just have your name written all over it.
