QUOTATION

My younger sister ask for my help to her assignment in Math, while I'm doing my pedicure I told her that you can answer it on your on but she insist to help her. But then, I can't do but to help. Here the problem...
"Match each verbal phrase under column A to its mathematical phrase under column B. Each number corresponds to a letter which reveal a quotation. A letter may be used more than once."

I told her just read the phrases and I'll just tell the answer while I'm doing pedicure. Were done answering the 14 items then my sister read what quotation revealed. But she said their is no quotation, when I saw her notebook and read it again here the result..

"ALL MEN ARE EQUAL"
