Apparently, my Pre-Calc teacher doesn't allow students to use a pen on assignments. I have no idea why.
The reason I use a Pen is because I hate using pencil. There are several reasons for this:
1) It's difficult to see
2) Pencils smear, which destroys the homework after a few day
3) Pencils require lead, which is a pain to reload
4) Good Mechanical Pencils get stolen often
5) IDK why, but when I use a pencil, I make more errors
6) With each error, I must use an eraser and the eraser shreds annoy me
That being said, I only carry a pen in my backpack and sometimes I when I don't finish my homework assignment at home, I must complete it in pen during lunch. This causes her to deduct points every time. I thought a teacher is supposed to teach, and assignments are a signal of how well a student has learned, not how well they fit the teacher's irrelevant templates.
Seriously, I have my homework assignment, done much more complete than what other students have. The content, the work, everything is there. In fact, my graphs are neater than 90% of what the other students hastily draw.
Is there something in the pencil that causes Math teachers to ban the usage of pen? (Last year, I had a Geometry teacher with a similar policy but he didn't care because I actually tried harder than the other students in the class.)
What's so important about a pencil?
