Chu Molin was helping his father-in-law outside, and Qin Xue went home to find her mother.
"Sis, you're back. Can you help me with this problem?"
Qin Xue was stopped by her sister as soon as she entered the house.
"Which problem."
Qin Xue took her sister's book and started to read it, then she explained step by step.
"So that's how it's done. No wonder I couldn't get it right."
Qin Jiale noticed that her sister had made a mistake in one of the formulae and calculations she had written.
"You need to spend more time studying and practicing in the areas you don't understand. As long as you plug the formula correctly, the problem will become easy. On the contrary, if the formula is wrong, no matter how many times you calculate it, it will still be wrong."
After Qin Xue finished speaking, she patted her sister's head and walked out of the room, leaving her sister alone to continue her work.
"Mom, is the baby asleep?"
