Question

In what way was the punch code useful

Answer 1

HERE IS YOUR ANSWER

I hate school." She always had to write them out in a punch code they made her learn when she was six years old, and the mechanical teacher calculated the mark in no time. The Inspector had smiled after he was finished and patted Margie's head. ... She had been hoping they would take the teacher away altogether

Punch codes are like binary numbers ( Computer language ) . Margie had to write her homework and test papers in punch codes so that the robot could understand it
