When we are in school, we do our best to learn the basics, such as reading, writing and arithmetic. Every teacher has their own style of helping us to get the hang of math, and sometimes, they may use methods that are somewhat out of the ordinary.

In the joke that you read below, little Billy is practicing his addition at home and his mother overhears the conversation. She can’t believe that he is using such a naughty word so she storms in to see the teacher to learn why. This is one of those jokes that will leave you laughing all day.

Little Billy was at home doing his math homework. He said to himself, “Two plus five, that son of a b!tch is seven. Three plus six, that son of a b!tch is nine.”

In that moment, his mother comes in and hears what he is saying.

“Billy, what are you doing? Why are you saying that?”

Little Billy answered, “I’m doing my math homework, Mom.”

She said, “And is that what your teacher taught you?”

He replied, “Yes.”

The next day, the mother, worried about the education her son is receiving, goes to Little Billy’s school to talk to the teacher.

The mother said to his math teacher, “I would like to know what you are teaching my son in math?”

The teacher replied, “Right now, we are learning addition problems.”

Billy’s mother asked, “And are you teaching them to say two plus two, that son of a b!tch is four?”

When the teacher stopped laughing she replied, “Not at all! What I taught them was two plus two, THE SUM OF WHICH IS four.”
