"11,19,27,14,17,3,16 ..." Meng Jing read carefully, "There is no connection!" Suddenly, her eyes lit up: "Yes! Didn't the teacher teach' simple algorithm'? I will try it with a' simple algorithm'. " Meng Jing took out the draft: "1 1+ 19 = 30, 27+3 = 30, 14+ 16 = 30,13+/kloc-0. Are all equal to 30. A * * * has four 30,4× 30 =120 (mm), and a * * * is 120 mm! " "Haha, Meng Jing is really smart." The fairy smiled.

"It's raining hard. Let's go to that ice cream shop to shelter from the rain. " Meng Jing said. The fairy nodded and they walked to the ice cream shop opposite. When they entered the ice cream shop, they took the menu and worried, "which one should I order?" Rainbow ice cream? Show off Bree. Or ... math ice cream? " The two of them said in unison: "Mathematical ice cream!" So, they bought four math ice creams. "Do you want ice cream, ice cream, ice cream or ice cream?" The waiter asked. "What's the difference?" Meng Jing asked. The waiter smiled: "It's all 2, 1. For example, the addition ice cream is 2+ 1 = 3 (yuan), and the subtraction ice cream is 2- 1 = 1 (yuan) ... "I know, I know, buy four subtraction ice creams. "Meng Jing interrupted the waiter." What a clever little cutie! "The waiter smiled and left." Why buy subtraction ice cream? The last time I ate additive ice cream, it was delicious! "Asked the little fairy. Meng Jing smiled and replied, "Don't you know? Minus ice cream to save money. " The little fairy suddenly realized.

After eating the math ice cream, they ate some other ice creams. When it was time to pay, Meng Jing touched her pocket: "No, I only brought 2 yuan money. How much did you bring? " The fairy touched her pocket and panicked: "I only brought 3 yuan! A * * * is 10 yuan, and we add up to 5 yuan. " "Nothing, nothing," the waiter pointed to the notice hanging on the wall. "Look there!" Meng Jing looked aside and saw a notice that read:

Thanksgiving special! When the consumption is over 10 yuan, 5 yuan will be deducted!

"Haha, just 5 yuan." Meng Jing happily paid the money.

At this moment, no one noticed that a thief took a pair of scissors in his hand and secretly cut off the Ping An jade around the little fairy's neck. Still humming in his mouth: "Peace jade is good and can be sold for 100 yuan. Divide the peace jade into two pieces and you can sell it for 200 yuan. Divide the peace jade into four pieces and you can sell it for 400 yuan ... "
