"Then what about the sum of the second and the second-to-last numbers?"
"Also 100!" Liang Chengcai's eyes lit up.
"Therefore, according to the distributive and associative properties, the final equation becomes fifty 100, leaving only 50 unmatched!" He said in surprise.
Lin Xiaoyue nodded. Her eyes were filled with admiration.
He understood with just one hint, so he must be very smart.
"That's amazing! I had to calculate for half a day to get the answer, but according to your method, the result can be obtained so quickly!" Liang Chengcai was so shocked that he stood up.
"Young lady, you're so talented!" He saluted Lin Xiaoyue.
Lin Xiaoyue waved her hand.
"I also learned it from someone." She said humbly.
The crystallization of thousands of years of wisdom, of course it's awesome in the eyes of ancient people.
