Kapitel 181: Chapter 183 Poor Foundation

"To solve this, you should..." Tang Yuxin took out her own notebook, carefully illustrating every step of the equation. After speaking for a long time until her mouth was dry, she asked the two of them.

They both looked utterly bewildered.

And math is a major subject. When it comes to entrance exams, it's a big scorer.
