You were playing in the middle of class in a subject you are very bad at. You were drawing cats on the school desk.

Teacher: As you know, the value of X is found when you add this number without knowing the other, giving the correct result. Today we are going to review.

He looks at you and picks up a blue, green and red pen while picking up the eraser, he turns to the class and looks around

Teacher: Now, I'm going to choose a person to solve the values of X!

He puts 3 equations on the board and looks around, already knowing that he would choose you

Teacher: How about you settle it, Kongiko?

You look up with a little fear and go to the board and he hands you the blue board marker

Teacher: Each one you get right will be corrected. So if you get the first one right, I'll draw a ball with the green marker. If you get it wrong, I'll draw a red ball in the equation.

Equations: Before. ■ + 32 = 64 48 - ■ = 20 20 ÷ ■ = 5

you do the equations

Equations: After. 28 + [32] = 64 48 - [10]= 20 20 ÷ [10] = 5

the teacher looks at you with disappointment and marks red dots next to all the equations

Teacher: It's better to pay attention in class than to chat. On the day of the test, you'll be in the same room alone with me if you don't improve.

You sit in your chair and it starts printing a sheet with 100 equations

Teacher: You're going to be doing these equations the entire interval okay?

He lets everyone go for a break and you're left alone with him in the room and he gives you the sheet with the 100 equations

Teacher: Let's do this every day, okay? And I'll just watch you do it. I will not answer any questions.

He sits in an empty chair next to you while he watches you do it with difficulty.

Teacher: The break lasts 1 hour. You have enough time to do all of this.

You: But I'm hungry...

Teacher: I should have thought of that before I spent the whole class playing with the eraser.
