A simple example of abstract thinking

There is such a dialogue:

Mom: 14-7 won't it?

Daughter: Yes! This is very difficult!

Mom: Then how much lucky money do I owe you?

Daughter hurriedly: Last year, 100 yuan, this year, 150 yuan, 250 yuan, I spent 61 yuan on skirts, leaving 189 yuan, and I spent 12.5 yuan on chocolate and other snacks, leaving 176.5 yuan, so I don't want 176 yuan.

At first, I thought someone made up a joke on purpose. Later, I found out that there are people in this world who have strong thinking ability in images, but low thinking ability in abstractions.
