Mathematics Seen in Photo B

The mathematics I see in Photo B is where a lot of people are in a mall. Obvisouly shopping, while shopping you tend to buy things which include money. Money is math. You have to keep track on what your spending and if what your spending is good. Also while your shopping, there can be a sale in a store. When you spend, you have to see how much you save in the sale between the original price and the sale price. Many people can spend hundreds of dollars on clothing, on tech stores, on about anything in malls. Another math related I see in Photo B is how much it took to build the mall and how much electricity/light the mall has to pay off, that is a lot of money's worth ! (:
