Imagine you have a big jar of jellybeans, and you want to know how many are inside without counting them one by one. Quants are like the smart kids who can use math and special tricks to figure out the number of jellybeans in the jar. In the grown-up world, quants are people who:

• Use math and computer skills to solve problems in finance, like figuring out the best way to invest money
