Six out of five adults don't understand fractions.
I just scraped by in high school algebra, and at the end of my sophomore year, the nun gave me a barely passing C minus and told me never to darken any math class again. I graduated from college magna cum laude, without ever taking math. But now, at the tender age of 70, I can look at hymn numbers at Mass and add them in my head, divide it by the number of hymns and come up with the average number. I’ve always said that if God wanted us to add, subtract, multiple and divide letters, he wouldn’t have given us numbers.
