Teacher is so Smart
After studying roman numerals for a short time, the teacher had given the class some free time. Sally's teacher walked up to her desk and saw that she had written:
XI + I = X
on her paper.
He was quick to point out her mistake. Sally protested, saying she had it right. After demonstrating what she meant, the teacher apologized and moved on.
