What's the use of studying mathematics well?

Because of the trip to Phoenix was unexpectedly cancelled, at noon my girlfriend and I went to Pizza Hut to eat pizza. We ordered a 12-inch pizza, but the waiter said it was sold out. So he said he would give us a 9-inch one plus a 6-inch one as a replacement.

I thought it was fine. 9+6=15, and 15 is greater than 12, right? Before I could agree, my girlfriend loudly protested and refused to accept the offer.

My girlfriend asked the waiter to give her a 9-inch pizza plus two 6-inch pizzas. I was thinking: don't be too greedy, I myself already felt a bit embarrassed. But at this moment, my girlfriend (a strong person) asked the waiter for a pen and paper, and she started calculating seriously while leaning on the table......
