Show your work
When you just cleared your calculator and your teacher says show your work now you have to go back and redo your work and then colapse from work.
Example:
Perfectionist teacher: jimmy show your work.
Jimmy: I JUST CLEARED MY CALCULATOR FRRRRRRRRRRIIIICK!!!
Perfectionist teacher: jimmy show your work.
Jimmy: I JUST CLEARED MY CALCULATOR FRRRRRRRRRRIIIICK!!!
