How is Math Used in the Real World?

Math is used all around us. Think about the times you round up each item in the shopping cart, add them together and add your 10% tax to get a rough estimate of whether or not you have enough money. Or what about that stylish pair of $100 shoes you bought that were marked as 50% off. Math is used all around us every minute of every day. Just think like a mathematician and you will see it as I do.
