This is normal level math... grade 11.

It's honestly a miracle that my teacher is still a teacher.. He got fired by his department leader, and then rehired by the principal because the principal felt sorry for his retarded son.

Pro Tip: I'm left handed and I use the mouse with my right hand. My mouse is also running at a constant 1600 DPI because I hate the company's drivers for it. Also, lol paint.

Pro Tip: All good hand-written material on the internet was scanned from paper, created with a tablet, or created with a mouse running a DPI so low that even your grandmother would find it slow.

Pro Tip:

God I's a sophomore in high school. I had this weird class where 1st semester is 2nd semester Geometry and the 2nd semester is 1st semester Algebra II. The only reason I fail is because I don't do the F*CKING work. I'm too goddamn lazy to do my F*CKING homework in any of my classes.
