Mistake

In a class, there was a teacher trying to teach her students the basic of mathematics. The story goes like this . . .

Teacher: Today, I'm going to teach you all subtraction and addition.

The teacher started writing on the blackboard with a white colored chalk.

Teacher: Anybody knows, what's the answer to, when 1+1=?

Student (a boy): Teacher it becomes 11.

Teacher: No it's not 11 the answer is 2.

Student: How is that even possible? Clearly when you add 1 next to another 1 it becomes 11!

Teacher: I get what you mean, but it's not like that. Now move on to another question. What is the answer when 1divides 1=?

The same student raised his hand.

Student: The answer is 1111 teacher!

Teacher: How can you get the answer that much?

Student: When you divided 1, automatically the number one becomes 11. It's like you're slicing that number 1 in the middle and it has a twin. Which means, there are 4 twins of number 1 altogether! Which makes the answer 1111!

Teacher: No! No! No! You're answer is wrong! I don't know where did you learn all of this boy. You better work on your maths skills.

Student: Teacher, how many eyes do you have?

Teacher: Of course I have two! What do you think I am? A pirate?

Student: You're wrong. You have four eyes! Including your glasses. I bet you don't see that because you're too focused on finding my mistakes.

Teacher: Get out of my class now!
